The Ajax WallSwitch is a wireless power relay designed to give you remote control over your electrical appliances while monitoring their energy usage. This compact device fits discreetly into a wall plate, an electrical panel, or directly into a device body, connecting seamlessly with Ajax hubs and range extenders to manage power across your space. It supports resistive loads up to 3 kW at 230 V or 1.5 kW at 110 V, with a maximum load current of 13 A, making it suitable for a variety of household circuits. Beyond simple switching, the relay functions as an electric power meter, providing real-time data on current, voltage, and overall power consumption. You can choose between bistable and impulse operation modes, with the latter allowing for an adjustable pulse duration between 0.5 and 255 seconds. The hardware is built for longevity, featuring a relay service life of 200,000 cycles and integrated protection against voltage fluctuations and overheating if the temperature in the wall plate exceeds 65°C. Measuring just 39 × 33 × 18 mm and weighing 30 g, the black unit is easy to install using the included mounting kit. It maintains a wireless connection over distances up to 1,000 meters in open spaces and delivers alarm signals in just 0.15 seconds. This makes it a practical choice for those who want to automate their home lighting or appliances while keeping a close eye on their electricity costs.
