Abstract

522,612. Snap-action switches. WALSALL CONDUITS, Ltd., and GOUGH, E. Dec. 12, 1938, No. 36173. [Class 38 (v)] The rectilinearly-moving contact member 29 is operated by rotation of a spindle 31 carrying a lug 42 which moves with lost motion between shoulders 41 on a member 35 controlled by a dead-centre spring 37 and the member 35 is connected with lost motion with an arm 44 which enters a slot in the contact member 29 and drives it. The member 29 consists of an insulating plate 29 carrying contacts 30 adapted to bridge pairs of fixed contacts 20, 21. Each contact 30 is V-shaped and its sides are slightly separated from the plate 29 as shown.
