WallSwitch
Power relay to control electrical supply remotely
Description
Power relay for remote control of power supply of the security system - Ajax WallSwitch
Power relays are one of the most common devices used in automation systems, especially in large enterprises.
What is a power relay | The principle of operation of the power relay
The Ajax WallSwitch acts as a switch, i.e. closes or opens the electrical circuit. The trigger is the tracking of certain current parameters, not manual control. The power relay can be switched under external influence. Power relays 12 Volts, 24 Volts or those operating on standard 220 Volt networks are considered the most reliable among electromechanical relay devices. Power relays of the universal type are contactors in additional electric circuits, and also switches of motors with power up to 4 kW at voltage to 400 V. Depending on the model and manufacturer, power relays operate on AC or DC. 220 Volt power relays are intended for use in AC networks only. Relays are designed for close installation without derating, the connection is not difficult. Installation of devices is possible on a DIN rail of standard width of 35 mm.
Power relays 12V, 24V, 220V are used in various technological processes at industrial facilities.
Depending on the design features, power relays are equipped only with normally open contacts or a combination of them with normally closed contacts. Power relays are in demand due to the following advantages:
- Productivity and reliability.
- The design is safe and well-thought-out.
- Various configurations of contact groups.
- Reduced resistance on contacts.
- Compact dimensions: devices are smaller than semiconductor relays, while switched loads remain significant.
- Easy installation, flexible installation options.
- Designed for easy installation on a DIN rail.
- Wide scope of application: from powerful electrical systems to low-power signal circuits.
Power relays are used in the following areas:
- Lifting platforms and mechanisms, compact elevators.
- Engineering systems of buildings and structures in which the installation of silent switching is required.
- Electrical installations, household appliances.

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.
- Surge protection icon Protects devices against overcurrent and voltage surges
- Impulse bistable icon Operates in bistable or pulse modes
- Energy statistics icon Allows controlling electricity consumption
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

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