Most relays and contactors are considered “fail safe.” Fail safe relays require coil power applied continuously to make sure the relay is switched. Once coil power is removed the moveable contact in a fail safe relay returns to its default position. Latching relays require a momentary coil pulse to change the position of the moveable. Continuous coil power is not required to keep the relay in a particular switched state. When the application circuit needs to switch a latching relay it sends a pulse to the coil to change the moveable contact position.

G60L Gas dielectric excellent for effectively bounceless make load applications.

Excellent for capacitive discharge and safety dump switch applications.

Latching coils for lower power consumption.
