Snap Relay, HO - Atlas Trains

About this part

Atlas HO snap relay, a double-pole, double-throw relay with an actuating mechanism driven by a momentary-power twin coil solenoid. Mount it anywhere, and with a few connections it can power the frogs on Atlas Mark 3 and Code 83 #6 turnouts. It can light trackside signals to show turnout position, run control panel lamps for remote turnouts, and handle selective siding control so sidings only get power when the points line up for them. It can also control X-sections automatically. The Atlas Complete Wiring Book covers that setup.
