Trip relay, monostables and latching
Trip relays, with reduced switching times (e.g. <10ms) compared to standard relays (e.g. < 20ms).

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.
