Ajax LightCore (2-Gang) Relay for LightSwitch
Summary
The Ajax LightCore (2-gang) is a smart dual relay component that forms part of the LightSwitch Jeweller system, designed to replace traditional 2-gang mechanical or touch switches with advanced smart home functionality. This dual-gang relay works seamlessly with the SoloButton (2-gang) to create a complete contactless lighting control solution that requires no neutral wire installation.
Using Ajax’s proprietary Jeweller communication technology, the LightCore (2-gang) provides reliable wireless communication up to 1,100 metres in open space, making it suitable for both residential and commercial applications. The device operates in pulse or bistable modes and can control two separate lighting circuits of up to 300 watts per segment, with built-in current and temperature protection for enhanced safety and reliability.

FAQ
Do I need a neutral wire to install the LightCore (2-gang)?
No, the LightCore (2-gang) is designed to operate without a neutral wire. It only requires a live wire connection, making installation much simpler and compatible with existing wiring configurations.
What is the maximum power load per circuit for the LightCore (2-gang)?
The LightCore (2-gang) can control up to 300 watts per individual segment, allowing for two separate lighting circuits each handling loads from 5 to 300 watts. For low-power lamps, a capacitor is included in the kit to be connected in parallel with the lighting device.
Can I control each lighting circuit independently?
Yes, when paired with a SoloButton (2-gang), each side of the switch can independently control its corresponding lighting circuit. You can also control each circuit separately through the Ajax mobile apps.
How does the contactless touch control work for both circuits?
When paired with a SoloButton (2-gang), each side of the switch activates when your hand gets as close as 15mm from the respective button surface. This allows independent contactless operation of both lighting circuits.
What is the communication range of the LightCore (2-gang)?
Using Jeweller communication technology, the LightCore (2-gang) can communicate with Ajax hubs at distances up to 1,100 metres in open space, making it suitable for large buildings and warehouses.
Can I use the LightCore (2-gang) in combined switch installations?
Yes, the LightCore (2-gang) can be used with CenterButton or SideButton components in Frame (2-4 seats) configurations for combined switch installations, allowing multiple switches to be installed in a single frame.
