ABSTRACT:
A miniature armature relay having a substantially flat header and a cover therefor. Attached to the header is an electromagnetic operator which comprises an electromagnetic winding and a reciprocatable armature therewithin which carries a disc-shaped contactor.
Mounting lugs are fixed to the header on opposite sides of the armature, and individually carry a stationary contact to be engaged by the contactor. Alignment means comprising a pair of anchor lugs on opposite sides of the armature, and a flexible member secured to the armature and such anchor lugs is also included. A biasing spring urges the armature to retracted position and the electromagnetic operator overcomes such spring in response to energization of the winding thereof.
