Instantaneous relays
The contacts of an instantaneous relay pull-in when the coil is energized and drop-out when the coil voltage is off.

Timer Relays
Time delay have additional electronic circuits, creating specific timing functions of the contacts.

Latching relays
The contact of a latching relay pull-in with a voltage pulse is applied on the coil and drop-out with another pulse. This can be done by using two coils asisted by a mechanical or magnetic locking mechanism.
