PRODUCT DETAILS

The Ajax LightSwitch (Dimmer) Jeweller is a smart touch light switch with an integrated dimming slider, and is made up of 2 components; the LightCore (Dimmer) dimmer core (not included), and the SoloButton (Dimmer) touch-sensitive panel for a single LightSwitch (Dimmer). It can be used to switch a lighting appliance on and off and adjust the brightness of the light. The smart dimmer light switch combines the reliability of professional security systems with a thoughtful user experience. The dimmer allows you to control the brightness of the lighting and adjust it according to your needs. It remembers the last adjusted brightness level and turns on the lighting devices with a preset brightness.

LightSwitch is good to use in the dark thanks to its soft backlight. The dimmer light switch can do more than just turn on lighting fixtures. It can also simulate the owner's presence and control curtains or blinds remotely with automation scenarios.

The dimmer is a part of the LightSwitch series. The smart touch light switch can replace any mechanical or touch switch, with the series offering one-gang and two-gang regular, two-way, and crossover versions. Devices can be combined as a set with other Ajax smart switches and/or outlets* and installed horizontally or vertically into one Frame side by side.

Please note: This is the front panel component only. For a complete LightSwitch you will also need the LightCore component which can be found here.
