Abstract

585,972. Snap-action switches. EDSON, B. Oct. 10, 1944, No. 19441. [Class 38 (v)] A snap-action switch comprises fixed stationary contacts 13, 14 between which moves a contact 12 on an arm 6, shaped as ir Fig. 7, flexed by an actuating plunger 30 and fixed at it right-hand end by a terminal rivet 10. A leafspring 18 which is fixed to or integral with the free end of the contact arm and is bowed by compression against a grooved stem 16 on the base, produces a dead-centre snap-action and also urges the spring 6 against contacts 13 when there is no pressure on the plunger 30. The lid 3 is located by a pin 28 passing through the body of the base, and lugs on the lid which co-operate with corresponding cut-out portions of the base. The contact arm is preferably made of beryllium-copper or phosphor bronze.
