Abstract
763,117. Snap action switches; switch covers. CRABTREE & CO., Ltd., J. A., WINTLE, T. D. G., and MIDDLETON, E. June 17, 1955 [June 23, 1954], No. 18370/54. Class 38(5) In an electric switch of the kind in which the cover 1 cannot be removed when in the "on" position a handle 7 is attached to a spindle which projects through a bush 4 in the cover and carries a pin 10 to which is attached a torsional snap action spring 11 the pin also engaging a sleeve 9, which is provided with slots 9a which receive a transverse pin 13 on a switch spindle 12; a bracket 2 secured to the cover and disposed over the sleeve 9 has an elongated slot 2b which will accept the transverse pin 13 of the switch spindle in the " off " position only, so that the cover and associated mechanism may be disengaged from the operating spindle only when the switch is "off." The snap action spring 11 has one end secured to the cover at 16 and the other end to a flat end 10a of the pin 10, the movement being limited by side projections 2d of the bracket 2. The handle 7 may be padlocked in either of the two operating positions to lugs on a front plate 15 (not shown). Specification 719,811 is referred to.
