Abstract

976,602. Momentary-contact switches; pressbutton retractive switches. CUTLER-HAMMER Inc. July 31, 1962 [July 31, 1961], No. 29347/62. Heading H2B. When trigger 12 is moved to the right against a compression spring 27, the lower sides of flanges 36d on an operating member 36 engage tabs 26c to depress a spring blade contact member 26 downwardly to make contacts 18, 32, but with continued movement in the same direction against the increased resistance of spring tabs 34b the flanges 36d move off the tabs 26c and allow member 26 to spring upwards and break the contacts, Fig. 8, such that when trigger 12 is released the flanges pass back under the tabs and thus do not actuate the contacts during the return movement. A spring-loaded ball 42 indicates the position at which contacts 18, 32 are made by engaging in a hole 46 formed in a frame 14 which provides a guide for movement of trigger 12.
