Abstract

940,615. Snap-action switches; switch covers. MIDLAND ELECTRIC MANUFACTURING CO. Ltd. May 1,1962, No. 16581/62. Addition to 785,947. Heading H2B. A switch having an interlocked cover 25 comprises the combination of a handle 27 and switch-actuating spindle 26 carried by the cover and a shield 19 secured to the switch and having therein an elongated slot 21 giving access to an angularly movable claw 15. The claw is connected to a linkage 18 which is in turn connected to an endwise slidable bar 10 which carries or operates contacts so that angular movement of the claw effects endwise movement of the bar. There is also provided a key piece 30 which is secured to the spindle 26 and which is engageable with the claw 15, the slot 21 and the key piece 30 being arranged so that the cover 25 can be opened only when the switch is in the " off " position. A further plate 31 is secured to spindle 26 and has an elongated member 32 pivotally connected to it and surrounded by a compression spring 34 which goes over centre to positively locate the handle in both its " on " and " off " positions.
