AJAX WallSwitch – Wireless 240v AC Control


Product Info

The device connects directly to the 110 V/230 V source and closes/opens the circuit on command. The relay can handle loads of up to 3 kW, which is enough to connect a very power-hungry device. Thanks to WallSwitch, this feature of the device may become known — it displays power consumption in the Ajax app.

  • Protects devices against overcurrent and voltage surges
  • Operates in bistable or pulse modes
  • Allows controlling electricity consumption


Connecting WallSwitch to the hub takes less than a minute — it’s enough to scan a QR code with the Ajax app. The miniature relay (39×33×18 mm) is easy to place in a recessed wall plate, the body of an electrical appliance, or an electrical panel. A flexible external antenna ensures stable communication.
