Abstract

844,646. Press-button retractive switches. ELECTRO-SNAP SWITCH & MFG. CO. Aug. 30, 1957, No. 27423/57. Class 38 (5). A retractive switch having snap action comprises an insulating casing with a cavity 15 across which a terminal member 25 extends to carry a trifurcated blade spring having side members 32 and bowed tongues 34 and 35 located in relatively displaced notches in the member 25. A contact 33 on one end of the spring is thus held into engagement with the upper of a pair of fixed contacts 23 mounted on terminal stops 20 which have extensions 21 projecting into recesses in the casing and its cover 16. Depression of plunger 26 overcentres the side members 32 with respect to tongue 34, snapping contact 33 into engagement with the lower fixed contact 23, and compresses reset tongue 35 such that on removal of pressure on plunger 26 the switch reverts to the condition shown in Fig. 1.
