Abstract
733,222. Two-part couplings combined with switches. PARSONS, Ltd., C. H., and HANDLEY, G. B. Nov. 6, 1952 [Nov. 7, 1951], No. 26033/51. Addition to 609,840. Class 38 (1). [Also in Group XXXVII] An interlocking switch and -plug-and-socket connector in which movement of an operating lever 10 about a pivot 11 rocks a mercury container 22 to control a circuit (see Group XXXVII), comprises a reciprocable member 30 pivotally connected to the inner end of the lever by a pin 21 and guided for movement by a slot 32 engaging a post 33. A pivoted pawl 38 is urged by a spring 34 to grip the earthing pin 40 of a three-pin plug inserted in a socket contact 36, this gripping action being released when the lever 10 is moved to the "off " position by an abutment 41 on the member 30 which moves to engage the pawl. To prevent closure of the switch when the plug is not in position an arm 43 pivoted at 44 is biased by a spring 48 so that an aperture 46 in a cranked-up end 45 thereof receives a lug 47 on the member 30. On insertion of the earth pin 40 a pivoted arm 42 is pushed out of the socket 36 which moves the arm 43 to disengage the lug 47. Specifications 708,942, [Group XXXVII], and 522,147 are referred to. The Provisional Specification refers to Specification 702,053.
