Abstract
A contact spring assembly for an electromagnetic relay has an armature, a plurality of movable contact springs, and a plurality of transfer contact spring sets and a plurality of make contact spring sets. The armature is centrally placed in the contact spring assembly. Each of the movable contact springs is formed integrally with a corresponding hinge spring, and the movable contact springs are disposed on both sides of the armature in such a manner as to extend in parallel along a longitudinal direction of the armature. The transfer contact spring sets and make contact spring sets are constructed from the movable contact springs. This construction allows the contact spring assembly to be assembled on an electromagnetic relay simply and with high accuracy, and permits reductions in the size and power consumption of the electromagnetic relay.
