Abstract

419,917. Snap -- action switches. BURGESS LABORATORIES, Inc., C. F., Madison, Wisconsin, U.S.A.-(Assignees of McGall, P. K. ; 413, Berwick Street, Orange, New Jersey, U.S.A.) March 13, 1934, No. 7916. Convention date, March 29, 1933. [Class 38 (v).] A snap - action switch comprises a leafspring 12 of the form shown in Fig. 2 supported at one end in cantilever fashion by a screw 16. The spring is formed with side arms 20 21 which are crimped at 210 and have the free ends fulcrumed at 23 in the ends of a U-shaped member 14 between the limbs of which the spring 12 is free to move. The free end of spring 12 is provided with a heavy contact bar 22 free to move between fixed stops 24, 25, either or both of which may be contacts. On depressing a plunger 15, the left hand part of spring 12 is depressed until it moves across the pivots 23 when the limbs 20, 21, acting in compression, cause the contact 22 to snap downwards. On release of plunger 15 the spring 12 returns due to its own resiliency. In modifications, the side arms 20, 21 are simple bowed springs in compression and may be formed of separate strips clamped to the strip 12 by the contact bar. The switch may also be operated by a pivoted stirrup carried on the outside of the casing and engaging the operating plunger.
