Abstract

620,972. Contact members for switches; electromagnetic relays. SVENSKA RELAFABRIKEN AKTIEBOLAG, VIGREN, S. D., and ZANDER, R. A. Feb. 5, 1947, No. 3467. [Class 38(v)] In a multiple spring contact assembly or " pile-up" the movable and " fixed " contact springs 6, 7, are substantially L-shaped, Fig. 1. The springs are assembled one above the other with the contact carrying limbs 1 pointing in opposite directions so that the contacts are interleaved whilst a space is left between the side or longer limbs. This space is used to accommodate an insulating lifting member 2 which operates the moving contact springs, and an insulating supporting member 3 which supports the fixed contact springs. These two members may be supported between blade springs 4, 5, Fig. 4. The dimensions of the contact springs are such that a wiping action between co-operating contacts is obtained.
