ABSTRACT:
A relay with plunger-type armature includes a resilient contact support, such as a conductive leaf spring, supported by a terminal in a manner affording substantial attenuation of contact bounce when engaged by an armature-mounted contact. Provision is made for insuring separation of the contacts upon reverse displacement of the armature. Specifically, a leaf spring may be fixed at one end to the base of a channel formed in the surface of a terminal plate. An overlying apertured insulator preflexes the spring and limits its displacement in the reverse direction. In a double-throw relay, the other "stationary" contact may be mounted on a resilient support, such as another leaf spring, for providing contact bounce suppression there as well.
