Abstract

853,951. Press-button retractive switches; snap-action switches. ILLINOIS TOOL WORKS. July 4, 1957, No. 21216/57. Class 38 (5). A switch comprises a spring-member having two parallel arms anchored together at one end carrying the movable contact and clamped to the base at the other end with one arm in tension and the other in compression, the latter being resiliently stressed into a shallow S-shape from a substantially straight shape when unstressed. As shown, two compression arms 82 with a central tension arm 78 are clamped to the base 12 at 86, the arms 82 engaging shoulders 20. The movable contact 94 normally engages a fixed contact 58 but can be moved to engage a fixed contact or stop 64 by depression of a button 100. The parts may be arranged so that the spring goes over-centre or so that it restores automatically on release of button 100.
