Abstract
655,390. Snap-action switches. IGRANIC ELECTRIC CO., Ltd. July 18, 1947, No. 19297. Convention date, Feb. 2, 1939. [Class 38(v)] A switch comprises a pivoted dolly 25 which engages the concave top of a member 27 enclosing a spring 22 which bears on a pivoted member 20. The pivot consists of a bent wire 17 the ends of which engage in openings in the cover 18. Member 20 engages in an opening in a longitudinally-sliding insulating block 13 which carries a contact 14 bridging fixed contact blades 33, 34. Each of the latter consists, Fig. 2, of an inclined arm 33d the lower end 33e of which forms the contact proper, and a vertical portion 33a which enters a groove 31d in the base. A clamping screw 32 for the lead passes through an opening in the part 33a and is held by a nut 35. Vertical movement of the contacts is prevented by the cover 29. A horizontal partition 36 divides the casing into two parts the lower one of which forms an arcing chamber.
