Abstract

856,222. Press-button retractive switches; actuation of switches; switch bases. AANDEWIEL, C. J. June 1, 1959 [June 4, 1958], No. 18668/59. Class 38 (5). The body 1 of a micro-switch comprises a block of transparent insulating material having conductors 2, 3 and 4 sealed therein and extending into a recess 5 containing snapaction mechanism and hermetically sealed by a cover 14 and a part 13. The part 13 serves as a sealing bearing for a U-shaped crank 10. which extends into the path of movement of a retractive press-button 12 accommodated in a second recess in block 1. This second recess is sealed generally by cover 14 and from the recess 5 by the part 13. Within recess 5 a resilient strip 6 is connected to conductor 2 and carries contacts co-operating with conductors 3 and 4, as shown. A leaf-spring 8 is interposed between strip 6 and an operating arm 7 secured to the crank 10 for movement therewith to give strip 6 a snap-action when button 12 is actuated. The body 1 is mounted in a metal casing 15 which also serves as a support for press-button 12.
