Abstract
654,715. Snap-action switches. YOUNG, S. G. April 30, 1948, No. 11513/49. Divided out of 654,693. [Class 38(v)] A dead - centre switch comprises a movable contactmember in the form of a conductive snapper 7 which has twc end members 10 two interrupted longitudinal side members 8, and a non - interruptec central member 13 secured to the base at 11, and a forked operating member 3 having recesses 15 engag ing the oppose( ends of members 8, which, as shown in Fig. 5, are corrugated. In a modification, (Fig. 5A, not shown), the tongues 8 are bowed instead of corrugated, and in a further modification, Fig. 9, the member 7 is operated by a pivoted member 51a having rods 54 engaging the central member 13 on either side of a projection 50. In Fig. 7, the central member 13 is corrugated and the members 8 non-extensible, the operating member being a forked push-button 25, engaging between the ends of the members 8 and the adjacent end member 10 which is secured to the base, and in a modification (Fig 8, not shown), the operating member is a double-ended pushbutton. The dolly 3 may be mounted on a fixed pin or supported in a shaped seating in the body. The operating member may have compressible portions which are engaged by the contact-member 7.
