Making an Already Installed Device Controllable
The WallSwitch plugs into a power circuit and controls it remotely. The connected device—light fixture, fan, pump, or space heater—does not need to be replaced or be “smart.”
Features
- Power supply: 110–230 V AC, 50/60 Hz
- Miniature size: 39 × 33 × 18 mm
- Indoor installation, in a flush-mount or surface-mount enclosure
Where to install it
Its dimensions allow it to fit behind an existing switch, in a wall box, or in the base of a light fixture. Nothing changes visually in the room; the wall switch continues to function normally.
WallSwitch or Relay
The WallSwitch directly switches 110–230 V AC power.The Ajax Relay provides a dry contact rated for 7–24 V DC for devices with their own control input—such as gates, door strikes, and automation systems.
