LightSwitch Jeweller is a smart touch light switch for indoor installation. LightSwitch can replace any mechanical or touch switch: the product line includes one-gang and two-gang regular, two-way, and crossover versions. Devices can be combined as a set with Ajax smart switches and/or outlets* and installed horizontally or vertically into Frame side by side.
Use the online Ajax switches and outlets configurator to assemble your custom set. Combine devices into a frame, pick the color, and download your configuration as PDF.
LightSwitch is installed without changing the electrical wiring of the object. The device does not require a neutral wire and works only from the power phase. The switch features a standard European form factor (55).
LightSwitch operates as a part of the Ajax system and communicates with the hub using two secure protocols. The light switch uses Jeweller to transmit alarms and events, and Wings to update firmware. The communication range is up to 1,100 meters in an open space.
The list of compatible hubs and range extenders is available here.
* Combinations with smart outlets are available only in horizontal orientation.
Design
LightSwitch is a prefabricated smart light switch. All switch components are purchased separately. Elements are connected mechanically without the use of tools. There are two LightSwitch formats in the Ajax product line: single and combined. Combined switches can be horizontal and vertical.
Single switch
A single LightSwitch is a prefabricated device that consists of two components:
- LightCore (2-gang/2-way) — relay for a two-gang two-way switch.
- SoloButton (2-gang) — touch-sensitive panel for a two-gang switch.
Combined switch
A combined switch consists of several LightCore relays and touch-sensitive panels installed in one frame with the appropriate number of seats.
- LightCore (2-gang/2-way) — relay for a two-gang two-way switch.
- LightCore (2-gang/2-way) vertical — relay for a vertical two-gang two-way switch.
- Frame (2 seats) — frame for two devices.
- Frame (2 seats) vertical — vertical frame for two devices.
- Frame (3 seats) — frame for three devices.
- Frame (3 seats) vertical — vertical frame for three devices.
- Frame (4 seats) — frame for four devices.
- Frame (4 seats) vertical — vertical frame for four devices.
- Frame (5 seats) — frame for five devices.
- Frame (5 seats) vertical — vertical frame for five devices.
- CenterButton (2-gang) — central touch-sensitive panel for a two-gang switch.
- CenterButton (2-gang) vertical — central touch-sensitive panel for a vertical two-gang switch.
- SideButton (2-gang) — side touch-sensitive panel for a two-gang switch.
- SideButton (2-gang) vertical — side touch-sensitive panel for a vertical two-gang switch.
Side touch-sensitive panels are installed on the right and left or on the top and bottom sides of the frame, while central touch-sensitive panels are installed in the center. For example, two side panels and one central panel should be used for three switches in one frame.
Colors
The product line includes 8 colors of touch-sensitive panels: White, Fog, Grey, Graphite, Ivory, Oyster, Olive, and Black.
The RAL colors below are as close as an approximation of the actual color. However, they may slightly differ, so please only use them as a guide to the color choice.
In the switch settings in Ajax apps, the color of LightSwitch can be selected. The color in the app does not necessarily have to match the color of the installed panel.
A PRO or user with admin rights can change the panel color anytime. For example, if an installer replaced the touch-sensitive panel or a user wants to set different colors for switches in the app to distinguish them.

Operating principle
LightSwitch is a smart touch light switch. It controls the lighting in three ways: manually, through smartphone and PC apps, and using automation scenarios.
LightSwitch is installed without changing the electrical wiring of the object. The device does not require a neutral wire and works only from the power phase.
LightSwitch can be used without adding to a hub. In this mode, it works like a regular touch switch.
LightSwitch can control 5 to 300 W lighting devices per one segment. The kit includes a capacitor connected in parallel with the lighting device for low-power lamps. See the installation section of this manual for details.
LightSwitch frame has an LED backlight. The backlight is not bright, so it will not disturb users even if the device is installed near a bed. If necessary, a PRO or user with admin rights can disable the backlight in Ajax apps.
The product line of devices includes one-gang and two-gang regular, two-way, and crossover light switches:
- LightSwitch (1-gang) Jeweller
- LightSwitch (2-gang) Jeweller
- LightSwitch (2-way) Jeweller
- LightSwitch (2-gang/2-way) Jeweller
- LightSwitch (Crossover) Jeweller
Devices combined in a frame can be installed horizontally and vertically. Vertical installation is supported only by relays, touch-sensitive panels, and frames with the label “vertical” in the name.
Use the online Ajax switches and outlets configurator to assemble your custom set. Combine devices into a frame, pick the color, and download your configuration as PDF.
If necessary, LightSwitch can also control other appliances. For example, one button can control the light, and the other one — room ventilation.
Manual control
LightSwitch allows to control the lighting when a hand is 15 millimeters away from the switch or when touching the touch-sensitive panel of the switch. Contactless control does not limit the possibility of use, even if hands are dirty or wet. The sensor reacts under any conditions. Therefore, the switch can be installed in crowded places: restaurants, factories, and offices.
The sensitivity of the touch-sensitive panel can be adjusted in the device settings in the app. Higher sensitivity ensures contactless operation, while lower values might require slightly touching the switch button.
The LightSwitch sensor instantly reads the signal and transforms it into an electric pulse. LightCore receives this pulse and activates a relay that switches on/off the lighting device or another connected load, such as a cooker hood.
The entire LightSwitch panel is touch-sensitive. Therefore, the lighting can be controlled by touching or reaching any part of the touch-sensitive panel with a hand.
Remote control
Control via the app
LightSwitch can be used to control lighting manually and remotely through Ajax apps.
Сlick on the switch in the LightSwitch field in the Devices 
menu in the Ajax app, and the state of the switch contacts will change to the opposite. The lighting will be switched off/on. This way, system users can remotely control the lighting. For example, switch on the light in the room in advance before entering the room.
The lighting can also be controlled in the Control 
menu. To do this, go to the Control menu and swipe up. All control devices added to the hub will appear in the list. Click on the switch in the LightSwitch field, and the state of the device contacts will change to the opposite. The lighting will be switched on/off.
Automation scenarios
Scenarios help automate security and reduce the number of routine actions. For example, set the lights to switch on by schedule or when disarming the security system.
LightSwitch supports the following types of scenarios:
- By alarm
- By arming/disarming
- By schedule
- By Button press
- By temperature
- By humidity
- By CO2 concentration
- By touching LightSwitch
Scenarios by humidity and CO2 concentration are available when LifeQuality is added to the system.
The system does not allow creating sequences of scenarios when the execution of one scenario activates the following one. This behavior is intended to prevent accidental endless looping of such scenarios.
Operation modes
LightSwitch can operate in one of two modes: bistable or pulse. The operating mode is set by a PRO or user with admin rights in Ajax apps in the device settings.
By default, LightSwitch operates in bistable mode. When controlling the lighting, it switches on/off.
When operating in pulse mode, the lighting can be switched on for the required time: from 10 seconds to 2 hours. This mode is useful, for example, if a user needs to switch on the lighting in the corridor for 5 minutes when disarming the security system.
Types of electrical protection of the switch
LightSwitch (2-gang/2-way) Jeweller has two independent types of protection: current and temperature.
Current protection is provided by the fast-blow 4 A fuse installed inside the device.
Temperature protection triggers if the switch temperature is greater than +60 °C. If this protection triggers, LightSwitch turns off the power and sends a notification to Ajax apps. The power supply is restored automatically when the switch temperature returns to normal.
Types of supported lamps
LightSwitch is compatible with most types of lamps and lighting devices. Detailed information on the LightSwitch operation with different types of lamps is described in the table.
| Type of lamp | Compatibility | Supported power | Maximum current | Comments |

Detection of lighting devices with insufficient power
LightSwitch continuously checks its power supply parameters. If LightSwitch controls the power of a lighting device with insufficient power (up to 5 W), the system will notify users. In this case, it is necessary to replace the lighting device with a similar one with higher capacity or to connect a bundled capacitor in parallel with the lighting device.
Jeweller and Wings data transfer protocols
Jeweller and Wings are wireless data transfer protocols that provide two-way fast and reliable communication between the hub and devices. The light switch uses Jeweller to transmit alarms and events, and Wings to update the firmware.
Firmware update
If a new firmware version for LightSwitch is available, the 
icon appears in Ajax apps in the Devices 
tab. You can launch the update in states or via the light switch settings. Follow the on-screen instructions to successfully update the firmware.
Information on firmware updates and new versions is available only for light switches that use the ReX 2 radio signal range extender and/or are added to such control panels:
Users will receive information about the new firmware version if the light switch is connected to the hub via ReX. However, the update is possible only after adding the light switch directly to the above control panels.
Firmware updates are not available for LightSwitch when operating via Hub Plus.
Sending events to the monitoring station
The Ajax system can transmit alarms to both PRO Desktop monitoring app and the central monitoring station (CMS) in the formats of SurGard (Contact ID), SIA (DC-09), ADEMCO 685, and other protocols.
Only events of lost connection between the switch and the hub (or range extender) are transmitted to the CMS. No other events are sent to third-party monitoring stations of security or monitoring companies. Use PRO Desktop to receive all switch events on the CMS.
Temperature protection triggering events are not sent to PRO Desktop as alarms.
When an alarm is received, the operator at the security company’s CMS knows what happened and precisely where to dispatch a rapid response team. The addressability of Ajax devices allows sending events to PRO Desktop or the CMS, including the device type, its name, security group, and virtual room. Note that the list of transmitted parameters may vary depending on the CMS type and the selected communication protocol for it.
The ID and number of the device can be found in its states in the Ajax app.
Selecting the installation site
LightSwitch is designed to fit into standard sub-sockets of the European form factor (55). The device should be connected to the power phase wire for proper operation. Connection of the neutral wire is not required.
Do not connect the neutral wire to the LightSwitch terminals. This can damage the device.
Signal strength
The Jeweller and Wings signal strength is determined by the number of undelivered or corrupted data packages over a certain period of time. The icon 
on the Devices tab indicates the signal strength:
- three bars — excellent signal strength;
- two bars — good signal strength;
- one bar — low signal strength, stable operation is not guaranteed;
- crossed out icon — no signal.
Check the Jeweller and Wings signal strength before the final installation. With a signal strength of one or zero bars, we do not guarantee stable operation of the device. Consider relocating the device, as adjusting its position even by 20 cm can significantly improve the signal strength. If the signal remains poor or unstable after relocation, consider using ReX or ReX 2 radio signal range extender.
Do not install the switch
- Outdoors. The device has an IP20 protection class. This may result in device failure or incorrect operation.
- On metal structures. This can lead to incorrect operation of the sensor: it may not respond to touch or give false triggerings.
- In rooms with humidity and temperature that are outside the permissible limits. This may cause a malfunction or incorrect operation of the device. The operating temperature range is from –10 to +40 °C. The permissible humidity is up to 75% without condensation.
- In places with low or unstable signal strength. This may result in a loss of communication between the hub (or range extender) and the switch.
Installation
Only a qualified electrician or installer should install LightSwitch. Do not switch on the power at the switches before installing the touch-sensitive panels. Also, do not try to register the device before installing the touch-sensitive panel, as it contains antennas needed to communicate with the hub.
Before installing the switch, ensure that the optimal location has been selected and that it complies with the requirements of this manual. When installing and operating the device, follow the general electrical safety rules for using electrical appliances and the requirements of electrical safety regulations.
For connection, use cables with a cross-section recommended by the manufacturer of the lighting device. LightSwitch (2-gang/2-way) Jeweller cannot be connected to electric circuits with a load exceeding 300 W per switch segment. The device does not require a neutral wire and works only from the supply phase.
After installing and connecting the switch, be sure to run the Jeweller Signal Strength Test and and Wings Signal Strength Test, and check the operation of the device: how it responds to touch, and whether it switches on/off the lights.
The installed touch-sensitive panel can be removed from LightSwitch with a flat screwdriver. To complete this, insert it into the hole from below (or from the left for vertical switches) and turn the screwdriver.
Ensure that the sticker shown in the image below has been removed from the touch-sensitive panel before installing it on LightCore. This is necessary for the correct LED indication of the device.

Adding to the system
Before adding a device
- Install the Ajax app.
- Create an account if you don’t have one.
- Add a hub compatible with the switch to the app. Set the required settings and create at least one room.
- Make sure that the hub is on and has internet access via Ethernet, Wi-Fi, and/or mobile network. This can be done in the Ajax app or by looking at an LED indicator of the hub: it should light up white or green.
- Ensure the hub is disarmed and does not start updating by checking its status in the Ajax app.
A PRO or user with admin rights can add LightSwitch to the hub.
Pairing with the hub
Do not switch on the power at the switches before installing the touch-sensitive panels. Also, do not try to register the device before installing the touch-sensitive panel, as it contains antennas necessary for communication with the hub.
LightSwitch should be within the coverage area of the hub’s radio network to pair with the hub. To work via the radio signal range extender, pair LightSwitch with the hub and then add it to the range extender. This can be done in the range extender settings. Detailed instructions can be found in the manual for the relevant range extender.
The hub and the switch operating at different frequencies are incompatible. The radio frequency range of the device may vary by region. We recommend buying and using Ajax devices in the same region. Please contact Technical Support for information on the operating frequency range.
LightSwitch only works with one hub. When paired with a new hub, the switch stops sending commands to the old one. When added to a new hub, the switch is not removed from the device list of the old hub. This must be done through the Ajax app.
To add LightSwitch to the hub:
- Install LightSwitch if you haven’t done so before.
- Open the Ajax app and select the hub where you want to add the device.
- Go to the Devices tab and click Add device.
- Enter the name of the device.
- Scan the QR code of the device or enter the ID manually. QR code is located on the rear panel of LightCore, the front panel of LightCore, and the device packaging. The device ID can be found below the QR code.
- Select a room and a group (if the group mode is enabled).
- Click Add.
If the maximum number of devices is added to the hub, you will get a notification about exceeding the device limit when you try to add the switch in the Ajax app. The number of devices that can be added to the hub depends on the control panel model and the Jeweller (or Jeweller/Fibra) settings.
- In a few seconds, LightSwitch will appear in the list of hub devices. Updating the device states in the list depends on the Jeweller (or Jeweller/Fibra) settings. The default value is 36 seconds.
If the connection fails, try again in 5 seconds. But this time, during the countdown, press and hold either switch button for at least 3 seconds.
If you press and hold the button of LightSwitch not paired with the hub for at least 3 seconds, the switch flashes green every second for one minute to inform you that it is not paired with the hub.
Functionality testing
After installation, test the operation of the switch: how it responds to touch and whether it switches on/off the light.
The Ajax system provides several tests to select the location of devices correctly. Tests do not start immediately. However, the waiting time does not exceed the duration of one “hub — device” ping interval. The default value is 36 seconds. The device ping interval can be changed in the Jeweller (or Jeweller/Fibra) menu in the hub settings.
The Jeweller Signal Strength Test Wings Signal Strength Test are available for LightSwitch. The test allows determining the strength and stability of the signal at the installation site.
To run a test in the Ajax app:
- Select the required hub.
- Go to the Devices tab.
- Select LightSwitch from the list.
- Go to Settings .
- Select a test:
- Run and perform the test using the prompts in the app.

LED indication
LightSwitch has a backlight that makes the switch visible in the dark. If the frame of the device is backlit, the light is off. When the light is on, the frame is not backlit. The backlight is not bright, so it will not disturb users even if the device is installed near a bed. The backlight can be turned off in the Ajax app if necessary.
If the temperature protection of LightSwitch is triggered or the touch-sensitive panel is removed, the switch flashes red every second.
To inform you that LightSwitch is not paired with the hub, it flashes green every second for one minute:
- when you connect LightSwitch to the power supply the first time;
- when you press and hold the LightSwitch button for at least 3 seconds.
Malfunctions
When a device identifies a fault (for example, there is no connection with the hub), the Ajax app displays a malfunction counter in the device field.
All malfunctions are shown in the switch states. Fields with malfunctions will be highlighted in red.
A malfunction is displayed if:
- Temperature protection was activated.
- A device with insufficient power is connected.
- An insufficient power supply is detected.
- There is no communication between LightSwitch and the hub (or range extender).
What to do in case of loss of communication with the device
LightSwitch may lose communication with the hub for the following reasons:
- Power is no longer supplied.
- The touch-sensitive panel has been removed (it has antennas on it, which are necessary for communication with the hub or range extender).
- The lighting device is faulty (for example, the incandescent lamp burned out).
- A device with insufficient power (up to 5 W) is connected.
- LightSwitch malfunction.
If an event about the loss of communication with the switch is received, the installer should check:
- Power supply of LightSwitch.
- Presence of a touch-sensitive panel on the switch.
- Operability of the lighting device.
If LightSwitch controls a lighting device with insufficient power (up to 5 W), it is necessary to replace the lighting device with a similar one with a higher power or connect a bundled capacitor in parallel with the lighting device.
Maintenance
Check the functioning of the switch regularly. Clean the enclosure from dust, cobwebs, and other contaminants as they emerge. Use a soft dry cloth suitable for equipment care. Do not use substances that contain alcohol, acetone, petrol, and other active solvents to clean the device.
