Abstract
500,670. Actuation of switches. STEVENSON, S. H., and HORSTMANN GEAR CO., Ltd. Dec. 24, 1937, No. 35737. [Class 38 (v)] In a time switch of a known type such as is described in Specifications 329,633, 331,083, [both in Class 38 (v)], and 373,554, a bell crank 17 is operated by a push button 18 against a spring 19 to move the spring contact member 5 to close the contacts. This arrangement allows manual operation of the switch for testing without changing the setting of the switch.
