Ajax LightCore (2-Way) Relay for LightSwitch
Summary
The Ajax LightCore (2-way) is a smart relay component that forms part of the LightSwitch Jeweller system, designed to provide two-way switching functionality for controlling lighting from multiple locations. This relay works seamlessly with the SoloButton (1-gang / 2-way) to create a complete contactless lighting control solution that requires no neutral wire installation.
Using Ajax’s proprietary Jeweller communication technology, the LightCore (2-way) provides reliable wireless communication up to 1,100 metres in open space, making it ideal for applications such as stairway lighting, hallway control, or any scenario where lighting needs to be controlled from two different locations. The device operates in pulse or bistable modes and can control lighting loads up to 600 watts, with built-in current and temperature protection for enhanced safety and reliability.

FAQ
What is two-way switching and when would I use it?
Two-way switching allows you to control the same light from two different locations, such as at the top and bottom of stairs, or at either end of a hallway. The LightCore (2-way) enables this functionality wirelessly without complex wiring.
Do I need a neutral wire to install the LightCore (2-way)?
No, the LightCore (2-way) 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 the LightCore (2-way) can control?
The LightCore (2-way) can control lighting devices ranging from 5 watts to 600 watts. For low-power lamps, a capacitor is included in the kit to be connected in parallel with the lighting device.
How does the contactless touch control work with two-way switching?
When paired with SoloButton (1-gang / 2-way) components at different locations, each switch activates when your hand gets as close as 15mm from the button surface. Both locations can independently control the same lighting circuit.
What is the communication range of the LightCore (2-way)?
Using Jeweller communication technology, the LightCore (2-way) 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-way) in combined switch installations?
Yes, the LightCore (2-way) can be used with CenterButton or SideButton (1-gang / 2-way) components in Frame (2-4 seats) configurations for combined switch installations, allowing multiple switches to be installed in a single frame.
