Abstract

1409183 Electric switches; contacts TAKANO PRECISION INDUSTRY CO Ltd 25 Sept 1973 [26 Sept 1972 26 April 1973 24 July 1973] 44834/73 Heading H1N In a method of making an electric switch having a pair of opposed contacts P, P<SP>1</SP>, Fig. 2, engaged by a movable snap-action contact H the terminal assembly A, B, C is stamped integrally with a web D which holds the parts accurately spaced until fixed in the casing E. The contacts P, P<SP>1</SP> are formed by first pressing an I-shaped insert 15<SP>1</SP>, Fig. 9A, of contact material such as silver into a pre-punched I- shaped hole and then punching out a slot 20, Fig. 9B, the faces of which are shaved to form accurately spaced contact faces S. The terminal A supports the movable contact spring F which is stamped from flat spring strip with a short tongue 26, Fig. 12, having a gap 27 which is engaged over opposed slots on the terminal A.
