ABOUT BRAND

Product Description

The WBT-912 Original Switch Wireless Transmitter allows homeowners and installers to retain existing wall switches while adding wireless smart control functionality. Installed discreetly behind a conventional switch, it converts standard push-button operation into wireless RF433 commands for compatible receivers controlling lighting and other connected devices.

Operating on 433.92MHz RF technology, the transmitter supports both ON/OFF switching and wireless dimming when paired with compatible dimmer receivers. Its advanced self-learning code system provides secure communication with up to 67 million unique code combinations, helping minimise interference with neighbouring installations.

Designed for potential-free contact connections only, the WBT-912 does not connect directly to mains voltage (230V). It operates from an included CR2032 lithium battery, making installation simple without additional power wiring. When used with a double rocker switch, both transmitter channels can be independently controlled for flexible lighting automation.
