RR7 - GE Remote Control Switching Relay

RR7 - Remote Control Switching Relay

Upgrade your low-voltage lighting control system with the General Electric RR7 Remote Control Switching Relay, a time-tested SPST relay engineered for reliability and longevity. Developed in the 1950s and still widely used today, the RR7 relay is the backbone of GE’s legacy low-voltage lighting system, including the iconic Touch-Plate control architecture. This mechanically latched relay is designed for central control lighting setups and is known for its rugged construction, energy efficiency, and ability to handle demanding electrical loads. Whether you’re maintaining an older system or building a new centralized control network, the RR7 delivers trusted performance with minimal maintenance and unmatched dependability.
