Abstract

791,307. Snap-action switches. HART MANUFACTURING CO. March 19, 1956, No. 8462/56. Class 38 (5). A lever-operated switch action comprises a contact member 30 pivoting on lugs 36 in notches 28 and a hollow dolly 54 in which slides a tubular member containing a spring 74 and carrying a wheel 76 which bears on a groove in the contact member 30. The tubular member comprises two halves 62 provided with longitudinal slots 66 through which pass a pivot pin 60 for the dolly, the spring 74 acting between the pin and shoulders 72 to urge the tubular member downwards. The dolly is mounted on a bushing 50 on a clamp 6 which overhangs and dips down a cover 4. A singlethrow switch is shown, alternatively the stop 24 may be replaced by a contact to provide a double-throw switch and the lugs 36 may be shaped to provide a central " off " position.
