Inspired by industrial systems that relied on relay switches to control motors lights and other industrial equipment vintage remote control wiring systems used relays to switch a current. Bryant uniline trigger switches if you have a low voltage bryant uniline system with thumb shaped trigger switches that fit into small rounded openings replacement switches and light switch covers are still manufactured and can be found under the sierra despard section.
Lutron Low Voltage Switching
Low voltage relay switch. Rr2 rr3 and rr5. These relays in turn were controlled by small light switches operating at a low voltage comparable to that of a doorbell. For standard low voltage unlighted switches both ge and bryant youll need to ge rr7 maintained relay switch which comes with 3 low voltage leads. Dzs elec 12v 2 channel highlow level trigger with optical isolation relay module fault tolerant design load ac 0 250v10a dc 0 30v10a circuit switch board 44 out of 5 stars 27 799 7. The rr7 relay is also a compatible replacement for a standard bryant solenoid relay and has a split low voltage 24v coil to move the line voltage contact between latched on and off positions. The rr7 relay and is the proper replacement for the following discontinued ge relays.
Enerlites ceiling sensor low voltage power pack for low voltage sensor and package self contained power supply relay system 120277v ac to 24v dc mpp 24 white by enerlites. Low voltage relays may not operate reliably if exposed to below freezing temperatures or to temperatures above 120 degrees. Switching relays that are too hot or too cold may not work properly.
