Ajax LightCore (2-way): smart light switch
The Ajax LightCore (2-way) is the two-way switch in the Ajax LightSwitch series: a smart light switch that combines comfort and security. The LightCore is the flush-mounted module containing the electronics and the relay; the touch panel is ordered separately in 8 colours.
The 2-way (two-way) switch controls one lighting group from two locations. Ideal for a staircase, a hallway or a bedroom where you want to be able to switch the light on when you enter and off again at the other end. Combine with a second two-way switch. This version is the horizontal variant, so that it fits neatly with your existing switch arrangement.
Completing the set: a working switch is this LightCore plus a LightSwitch Button horizontal (the touch panel) in your colour. Please note: the Ajax CoverPlate is a blanking plate without a touch panel and does not fit on a LightCore.
What the LightCore (2-way) does
Touch or contactless
A large touch panel switches the light. You do not even need to touch it: hold your hand within 15 mm of it and the light switches on or off. Soft LED lighting helps you find the switch in the dark.
No neutral wire required
The LightCore works on the live wire only and fits in your existing flush-mounting box. You replace your old switch without changing the wiring. A capacitor is included for low-power lamps.
Touch panel in 8 colours
The panel (Button) is ordered separately in eight colours and can later be swapped without switching off the power: view the horizontal LightSwitch Buttons. Combine several switches or sockets in a Frame, or build your set online.
Automation scenarios
Have the light follow a schedule, switch on when you disarm the alarm, or respond to an event. An off timer switches the light off automatically after a set time. You manage everything in the Ajax app.
Built-in security
The LightCore protects itself against overcurrent (above 2,6 A) and overheating (above 60 °C): it switches off the power and sends a notification to the app. A child lock prevents accidental switching.
Reliable via Jeweller
Wireless Jeweller connection with two-way communication and encryption, up to 1100 m in open space to your Ajax hub. You pair it by scanning a QR code; installation takes about 7 minutes.
Build your Ajax switch set
With the Ajax configurator you can put together a set of switches and sockets: drag the components into a cover frame, choose the colour and send your configuration directly to us or save it as a PDF. Useful for seeing in advance what your set will look like.

The LightCore modules compared
All LightCore modules share the same operation, the same touch panel in 8 colours and the same installation without a neutral wire. They differ in how many lighting groups they switch and from how many places you control them.
| Model | Function | Light groups | Operation from | Dimmable | Power |
|---|---|---|---|---|---|
| 1-voudig | Single-gang switch | 1 | 1 point | No | 5-600 W |
| 2-voudig | Double switch | 2 | 1 point | No | 5-600 W |
| 2-way | Two-way switch | 1 | 2 points | No | 5-600 W |
| 2-gang/2-way | Double two-way switch | 2 | 2 points | No | 5-600 W |
| Crossover | Intermediate switch | 1 | 3+ points | No | 5-600 W |
| Dimmer | Dimmer | 1 | 1 point | Yes | 8-150 W (VA) |
Not sure which variant you need? If you are replacing a standard switch like for like, choose the same function as your old switch. For a lamp operated from two locations, choose 2-way, and for three or more locations the Crossover. If you want to dim, choose the Dimmer.

Frequently asked questions
Is the touch panel included?
No. The LightCore is the flush-mounted module. You order the touch panel (SoloButton) separately, in one of 8 colours (horizontal LightSwitch Buttons), so that you can match the colour to your interior. With a Frame you can combine several switches or sockets in one cover frame. Please note: the Ajax CoverPlate is a blank cover without a touch panel and does not fit on a LightCore.
Do I need a neutral wire?
No. The LightCore works on the live wire only and fits in a standard flush-mounting box, so you replace your old switch without changing the wiring. A capacitor is included for low-power lamps.
Does this work without an Ajax alarm system?
The LightCore is a Jeweller device and requires an Ajax hub to work. You then control and automate the light in the same Ajax app as your security system.
Which variant do I need?
If you are replacing a standard switch, choose the same function: single, double or two-way switching. If you want to control a light from two places, choose the 2-way; from three or more places, choose the Crossover. See the comparison table above.
