A Relay Rack is a 2-post aluminum or steel structure with either EIA standard (round) mounting holes or universal (square) mounting holes.

Impulse Relays Impulse relays are a form of latching relay that transfers the contacts with each pulse. Many impulse relays are made up of a magnetic latch relay and a solid state steering circuit that, upon application of power, determines which position the relay is in and energizes the opposite coil. The contacts transfer and hold that position when power is removed.
