Zusammenfassung:FIELD: railway transport; railway signalling and communication. SUBSTANCE: proposed device has electrically operated timer, auxiliary relay with normally closed contact, time relay, signal lamps and terminals on device upper panel to connect the device to terminals of main and standby feeder circuits. When changing over supply from main feeder to standby feeder and back, auxiliary relay switches on timers which defines time of feeder switching. Time relay is used to check closing of light signals for required 1.3 s time period. EFFECT: possibility of checking interruption of supply on interlocking stations without re-equipment of stations. 1 dwgr
