A typical application
Add another switch without changing the style.
Use a switch plate that matches the rest of the room, with the battery module behind it. The receiver can work with an existing wired switch so both locations control the same lights.

Before you order
Check it suits the installation.
Check the available space and the load on each receiver. Walls and metal enclosures can reduce wireless range.

What it is:
A simple kit that lets you control your lights wirelessly without complex installation. Keep the same style as your existing switches - no drilling or complicated wiring needed.
How it works:
When the battery-powered switch module senses a change in the attached switch, it transmits to the receiver to switch the lights (see the video).

Inside the box, you will find:
- Wireless Receiver with integrated relay.
- Wireless Switch Modules including AAAA batteries.
- A Wiring Guide and Installation Instructions.
Installation options:
- Standalone setup: Connect the receiver directly to your lights to use wireless switches only.
- Add on to an existing switch: Connect the receiver to your current switch to use both the physical switch and wireless switch in a 2-way arrangement.
Quick tip: Already have a light switch? You only need the 1-transmitter kit to add another switch location for a 2-way setup. View the wiring diagram here.
Key features:
- No WiFi needed.
- Switch and receiver come pre-paired.
- Order multiple transmitters to switch lights from different locations.
- Signal works through walls up to 15 meters away.
- Use multiple kits in the same location without interference.
- Long battery life (5 years).
- Reliable connection with no interference from other wireless devices.
Tips for best use:
- Contactors and relays with AC coils can emit electromagnetic noise. If you intend to use such equipment nearby, ensure that there is at least 600mm separation from the receiver.
- Ambient temperature maximum is 45°C. Avoid enclosing the receiver with sources of heat like drivers, transformers, or luminaires.
- Metal sheeting can reduce the wireless range. Where possible, avoid using metal enclosures to house the units.
- Need to control gates or other momentary pulse loads? Contact our support team and we'll provide a special version designed for this purpose.
