An electromagnetic relay is described of the type wherein, upon energization, an armature, while being attracted to a yoke, is repelled by a flux plate and wherein parts of the magnetic circuit are utilized for electrical conduction. A coil form and plug-in shaft are provided for holding the relay windings and the magnetic circuit parts. Projections are provided for defining the position relationships between the relay windings and the magnetic circuit parts.

Electromagnetic relay

The present invention is directed to an improved electromagnetic relay having means for eliminating the chatter or bounce of the relay armature upon the movement of the relay armature from its energized position to its rest position, that is, the releasing or returning movement of the relay armature. An armature stopping means is formed by two resilient strips which deflect in response to the returning movement of the relay armature. This deflection of these resilient strips stores energy in these resilient strips for returning the relay armature to its initial rest position. In addition to these two resilient strips, the armature stopping means of the present invention includes means for generating independent counter forces which oppose the deflection of these resilient strips. One of these counter forces is a frictional force generated by the abuttment of a bent flange forming part of each of the resilient strips against rigid mounting elements for mounting the two resilient strips. Another counter force is generated by additional bent flanges which connect these resilient strips to the rigid mounting elements. Finally, the counter forces generated by the present invention are influenced by the bending strengths of the resilient strips.
