ABSTRACT:
A relay has an abutment mounted adjacent its armature for movement therewith. A spring-biased tapered pin engages the abutment when the relay is energized. This causes the relay to maintain a latched, first switch state. An electromagnetic releaser is then energized which displaces the pin thus freeing the armature. A spring returns the armature to an unlatched position whereby the relay is set to a second switch state.
