Safety Relays

Safety Relays have at least one normally closed contact and one normally open contact. The normally closed contact and the normally open contact are never closed together. If a normally open contact is welded the corresponding normally closed contact is not able to close when switching off the supply voltage.

For example Safety Relays could be used in lift controls to ensure the lift only moves when the doors are closed.
