Abstract
777,348. Switches held set and freed mechanically. GENERAL ELECTRIC CO., Ltd. June 8, 1955 [June 8, 1954], No. 16807/54. Class 38(5) [Also in Group XI] In a battery lamp switch of the kind comprising a strip-like contact member 5. located within the battery casing 1 so that it can be deflected downwardly on to the reflector 2 to complete the bulg circuit by the depression of a button or like member 9, the button or like member is attached to the contact strip 5, and the spring 13 which biases the button to the "off" position acts also to bias the contact strip to its "off". position. In the example the flame-proof switch of the torch described in Specification 502,566 is modified by providing the lower end of the shank 8 of the operating button 9 with a part of reduced section to engage within a longitudinal key-hole slot 7 intermediate the ends of the contact strip 5. The helical spring 13 is located in an annular recess in a brass insert 11 and engages the bottom edge of an annular wall 12 of the button, which is depressed by operation of a sliding cam member 14, as in the invention. of the prior Specification referred to.
