Abstract

915,934. Press-button retractive switches. FANSTEEL METALLURGICAL CORPORATION. Aug. 21, 1961, No. 30128/61. Class 38 (5). A snap-action switch comprises a base 18 having a contact-actuating spring 26 fixed thereto at 28, spring 26 having a longitudinal slot 34 extending for a major portion of its length and a preformed unstressed raised convex portion 38 disposed about the slot and opposite to an actuator 16, whereby depression of actuator 16 causes both lateral and longitudinal bowing of spring 26 such that it flexes about a lateral groove 40 and makes contact 27, 21, while breaking contact 23, 27. Base 18 has shoulders 31 abutting the sides of spring 26 and forming a channel 30 therebeneath into which depress the inner edges of slot 34 when actuator 16 is depressed.
