ABSTRACT:
The electro-magnetic relay comprises a contact block which is structured to uniformly maintain the contact resistance between the terminals of two circuits. Fixed contacts are provided for each of the terminals of the two circuits and each of two sets of a pair of movable contacts in positions corresponding to these is supported by two both-end-supported movable springs. An insulation sheet and a press spring are overlapped over the two movable springs and disposed as a bridge. A pair of tongues are formed on the press spring by a Z-character shaped cut and by an armature pressing their tips, the insulation sheet and press spring transforms to an upward concave shape, the two movable springs bend and are taken in inside while inclining and the movable contacts touch the fixed contacts while sliding.
