SER65021 - Integrated switch with 2 3A outputs

Product Description

The complete generic 2-output 3A switch is a wall-mounted device, mains-powered, with a built-in control input, designed to control lighting, dimming, shutters, ventilation or chime within the Bluetooth Mesh ecosystem.

Unlike the micro-module, there is no need to keep an existing switch upstream: the control button is built into the product. Motion detection can also be configured as an option.

The product includes all of the range’s general functions: status LEDs, Reset button, energy consumption metering, safety functions (overheat alert, power outage, zero-load detection), full Bluetooth Mesh connectivity (Proxy, Relay and Friend roles), voice assistant compatibility and software updates via the app.
