Abstract:
A moving contact arrangement, for a relay, for example, which allows for selective normally open and normally closed contact orientation with respect to fixed contacts by rotative movement between two opposite positions of a bridging bar carrying the moving contacts about an axis substantially parallel to and coextensive with a straight line connecting the moving contacts.
Abstract:
A relay switch arrangement having split housings associated with and divergently movable with respect to a base and to each other and detent means provided therebetween to allow the housings to be opened and to be maintained open against the forces tending to cause closure thereof so as to allow for ease in servicing of the magnetic frame, coil and armature-moving contact assembly of the relay switch arrangement which are encompassed by the base and the housings.
Abstract:
An arrangement for the magnetic frame and armature of a relay which upon impact of the armature against the frame allows for a wiping action between the engaging faces of the frame and the armature.
Abstract:
A relay and a relay-adder combination incorporating a constant force actuating arrangement allowing for the use of the same coil in both configurations whereby a reaction force which is encountered in the actuation of the relay per se is bypassed in the actuation of the relay-adder combination and is replaced by the force which is encountered in the actuation of the adder and which is equal to the reaction force.
