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.
