Abstract
933,765. Press-button retractive switches; snap - action switches. MINNEAPOLISHONEYWELL REGULATOR CO. Oct. 6, 1959 [Oct. 13, 1958], No. 33863/59. Class 38 (5). A snap-action switch comprises a rigid or spring arm 22 pivoted at A on a terminal 16 and pivotally connected at B to a rigid or spring arm 26 carrying a contact 27 co-operating with fixed contacts 17b, 18b, a C-spring 35 engaging arm 26 at point E and a fixed support 30 at D. When a button 40 is depressed, the dead centre position between points B, D and E is passed and the contact moves with a snap. When the pressure is relieved, the spring 35 or a separate spring restores the parts. Alternatively, a separate resetting mechanism may be necessary.
