Set the light to suit the moment.
LightSwitch (Dimmer) Jeweller brings touch dimming and Ajax app control to compatible lighting. Adjust brightness for everyday activities or use configured scenarios as part of the room’s routine. The lamps, electrical load and installation components are checked together so the dimming arrangement works as intended.

Set the light to suit the moment.
Match the mechanism to the circuit.
Switch and dim compatible lighting with the touch panel, the Ajax app or configured scenarios.
- Connected load: 8–150 VA for dimmable LED or incandescent lamps; 20–150 VA for halogen.
- 230 V, 50 Hz; no neutral wire is required at the switch.
- Use one lamp technology on the connected load. Fluorescent lamps, smart lamps and lamps with a built-in controller are not supported. The dimmer is not a general-purpose 600 W switch.
The mechanism, front and frame are selected as a complete assembly. Wiring and lamp compatibility must be checked for the actual installation.
The right brightness, every time.
Slide, hold or use the app.
Adjust brightness on the panel or in the Ajax app. The switch remembers the last brightness level. Set the minimum from 1–90% and the maximum from 11–100% to suit the lamps and avoid unwanted flicker or glare.
A separately supplied Bypass (Dimmer) [55] may be required if a compatible lamp flickers or does not work correctly. Have the installer assess the load; the dimmer consumes up to 0.25 W.
Easy to find. Easy to use.
A broad surface for everyday control.
The large touch surface is easy to use, including with a gloved hand. Use the dimmer’s brightness control to set the light level.
Useful controls, wherever you are.
Control the connected lights in the app.
See the light state and operate it from the Ajax app. Local touch control also works without a hub; app control and automation require a compatible hub and a working system connection.
Choose when touch control is available.
Enable childproofing in the app to disable local touch operation. App commands and configured scenarios remain available.
Switch off after the time you choose.
Set an automatic switch-off timer for lights that should not stay on indefinitely. The selected interval is configured in the Ajax app.
Let one action start a routine.
Use the switch as a trigger for other compatible Ajax automation devices. Each controlled load needs its own suitable actuator; a lighting output is not a direct curtain or blind motor controller.
Lighting that follows your routines.
Scenarios run through a compatible Ajax hub. Temperature, humidity and CO₂ triggers also need the appropriate sensor; humidity and CO₂ scenarios require LifeQuality.
Make a home look occupied.
Schedule connected lights to turn on and off while you are away. Choose the rooms and times in the Ajax app, then check the routine at the property.
A secure link to your system.
Jeweller for events. Wings for updates.
Jeweller carries commands and events; Wings delivers firmware updates to this switch. The specified communication range is up to 900 m in open space.
Walls, metal and the mounting position affect coverage. Test signal strength at the installed position. Device authentication and encryption protect the link; loss-detection timing depends on the configured polling interval and missed-packet threshold.
Reach the rooms your system needs.
Plan the radio path through the building.
A compatible range extender can connect a switch where the hub’s direct radio signal is insufficient. ReX 2 can use Ethernet as an alternative connection to the hub. Choose a supported combination and test it at the installed position.
Hub capacity, regional radio version and the required protocols determine the supported setup. On models with Wings, verify the firmware-update path as well as event communication.
Fit the assembly. Set up the light.
Install the correct components.
A qualified electrician should isolate the mains, verify the circuit and load, and fit the matching LightCore, panel and frame using the exact model’s wiring diagram. Fit the touch panel before testing the installed assembly.
For indoor use: −10 to +40 °C, up to 75% relative humidity without condensation, IP20. Assess whether Bypass (Dimmer) [55] is needed for the selected lamps.
Find the right light switch.
Compare LightSwitch models by the lights you want to control, the wiring at each position and whether you need dimming. European [55] and North American [120] models can be compared, but their voltage and components are not interchangeable.
