Abstract
426,094. Snap action switches. BECKER, Ltd., G., Ampere Works, Wembley Park, Middlesex.-(Vedder Ges., Geb. ; Schalksm³hle, Westphalia, Germany) March 14, 1934, No. 8093. [Class 38 (v)] A quick - action switch has an insulating contact arm 7 pivoted by an upstanding central part on a pin 3 which serves to hold in position a resilient arm 30, 31 having a curved central part 32 engaging a recess in the arm 7. Push buttons 33, 34 passing through holes in the cover bear on the resilient arm 30, 31. When the button 33 is depressed the arm 30, 31 is strained until the free end or a part 30<1> engages the contact arm positively to disengage a spring-pressed ball 11 from a recess 10 in the base of the contact arm, which then moves rapidly due to the resilience of the arm 30, 31 and the reaction of the ball 11 on the lower surface of the contact arm. Small compression springs 35, 36 may be placed between the contact arm and the resilient arm 30, 31 to assist the quick action.
