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 with DIN Holder. A flexible external antenna ensures stable communication.

WallSwitch Jeweller
WallSwitch is installed in electrical circuits to control the power supply of connected devices. It can function as a momentary or latching switch, with adjustable operating modes in Ajax apps. In pulse mode, activation lasts from 1 to 255 seconds, and relay states can be normally closed or normally open. WallSwitch supports automation scenarios like changes in security mode, scheduled actions, alarm reactions, and responses to temperature, CO2 concentration, humidity changes, and pressing LightSwitch.
Remote power supply control
The Ajax system provides the possibility to configure automation devices and Ajax WaterStop Jeweller in response to an alarm, armed mode change, schedule, or temperature. The security can be programmed to change the security mode by schedule, and the automation device can react to the LightSwitch or Button Jeweller press. Additionally, the user can control automation devices from the KeyPad TouchScreen Jeweller, KeyPad TouchScreen Fibra, KeyPad Outdoor Jeweller, and Superior KeyPad Outdoor Fibra.

Overview:
WallSwitch is a power relay to control 110/230 V~ power supply remotely. The relay power supply is not galvanically isolated with terminal blocks; therefore, WallSwitch switches only the power received at the power supply terminal blocks. The device has an energy consumption meter and features three types of protection: voltage, current, and temperature.
WallSwitch controls the power supply of electrical appliances connected to the circuit with a load of up to 3 kW using Ajax apps, automation scenarios, the function button on the relay, and by pressing Button.
WallSwitch is connected to the Ajax system via the secure Jeweller radio protocol. The communication range is up to 1,000 meters in an open space. The device works only with Ajax radio signal range extenders and hubs.
Key Features:
Control via smartphone
The user can set up the relay configurations and receive notifications in an Ajax app.
