Railway, Rolling stock

Forcibly guided contacts

The contacts are mechanically linked. These relays use special features to ensure the make contacts (normally open) cannot assume the same state as the break contacts (normally-closed).

Latching

Relay with 2 latched contact positions. The contacts change state with an electrical pulse supplied by one of the 2 power coils. To restore the starting position of the contacts, the other coil must be powered.

Time delayed, pick-up, drop-out, logic

The contacts change status with time delay T with respect to the energization or de-energization of the relay input circuit. Logical function relays can be used for various functions, including CYCLIC, ONE-SHOT, etc.
