GE Model RR-7 isa mechanical latching-type unit requiring only momentary 24 VAC switch circuit pulses to open or close line voltage circuits.
All GE low voltage relays may be used to full-rated capacity for tungsten filament, ballast, or resistive loads.
The relay employs a split low-voltage coil to move the line voltage contact armature to the on or off latched position. The on coil moves the armature to the on position when a 24 VAC control signal is impressed across its leads.
This is analogous to a magnet attracting the handle of a standard single-pole switch to the on position when energized.
The armature (handle) latches in the on position and will remain there until the off coil is energized, drawing the armature into the off position. This control operation provides several key control features:
The relay always goes to the state commanded. For example, multiple off commands will simply keep the contacts in the off position.
Since the relay latches in the on or off position, power outages do not result in a change of state.
Minimal power consumption
Control power is only required when the relay changes state.
Additive control functions
Pulse control signals coupled with latching allow any number of switches or electronic control devices to operate the same relay. The relay position is always dictated by the last signal.
Important Considerations and Restriction

Purchased this to replace a defective relay that lasted less than a year. The original relay has lasted over 40 years in a residential application. I am hoping this one will last as long as the original. Time will tell so its too early to know if the first replacement was a fluke or the complete lot is defective.
