Remote power supply control

Purpose
Safeguard in the power grid
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

Installation
No extra effort
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.
Always in touch
We developed the Jeweller radio protocol to ensure uninterrupted interaction of all security system devices. The radio protocol uses frames to synchronize device communication, authentication to prevent forgery, and encryption to protect against hacking.
- Two-way communication at a distance of 1000 meters
- 5 ReX radio signal range extenders in the system
- Command delivery in0.15 s
- Adjustable ping from 12 s
