ABSTRACT:
An electromagnetic solenoid relay in which the plunger armature is biased to its at-rest position by a spring of strip metal having an arcuate portion extending between an anchorage portion and an arm portion in engagement with the armature. The armature and spring are relatively loosely held together in operative relation to permit ready alignment of the armature with the relay electromagnet. A movable contact on the spring at one end of the armature cooperates with a stationary contact on a terminal of ferromagnetic material which forms a portion of the electromagnet magnetic flux path to provide a magnetic blow-out effect. The ferromagnetic bracket of the electromagnet is employed to retain major component parts of the relay in assembled relation.
