Abstract

1,096,160. Mechanical switches. VEEDER INDUSTRIES Inc. Dec. 6, 1966 [Jan. 5, 1966], No. 54478/66. Heading H2B. [Also in Division F2] A selector switch comprising a rotary brush 20 having bridging contacts 18, 19 biased into contact with a printed circuit plate 14 is operated by a ratchet wheel 22 that drives the brush 20 and a pair of drive pawls 46, 48 an flexible fingers 50, 52 forming part of a unitary actuator 44. On manual depression of a button 74 of the actuator against a spring 80, pawl 46 drives wheel 22 counter-clockwise while pawl 48 is flexed downwardly to slip over the teeth. On releasing button 74 it returns to its normal position by spring 80 and causes pawl 48 to drive wheel 22 counter-clockwise while pawl 46 is flexed to slip over the teeth. A part 86 of the actuator engages the ratchet teeth when stationary to prevent overthrow during rotation. An indicator wheel 30 visible through a window 34 is driven by wheel 22 through gearing 40, 42.
