Abstract

851,933. Contact members for switches; electromagnetic relays. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 16, 1957 [May 17, 1956], No. 15636/57. Class 38 (5). A contact assembly (Fig. 4) for an electromagnetic relay has fixed members 16, 18 held in an insulating base 5 and spring contacts 20 each biased so as to bridge a pair of members 16, 18. An actuator 13 holds one or other of the springs 20 away from the contact 18. One end of each spring 20 is held in a recess 24 in the member 16 by its own resilience. A number of contact assemblies are operated by one actuator 13 attached to a U-shaped armature 9 the ends of the limbs of which are pivoted at 10 on the limbs of a spring 11 riveted to an E-shaped core 3 and having legs 14 biasing the armature and actuator 13 in a clockwise direction. Energization of a coil 8 on the centre limb of the core moves the armature against the bias of the spring legs 14 to operate the contacts each of which may comprise two wires 20. The outer core limbs are riveted at 4 to the base 5.
