Abstract
664,131. Tumbler switches. ASHLEY ACCESSORIES, Ltd., and EVERITT, L. H. R. Nov. 11, 1949. No. 28916/49. Class 38 (v). A dolly-operated switch has its pivoted spring-urged contact member so arranged that the lost motion between the dolly and the contact-member is eliminated in both the "on" and "off" positions. In Fig. 1, the contactmember 12 is acted on by a spring 15 and in the "on" position pivots on one or a pair of fixed contacts 13, and in the open position, shown dotted, pivots about the point 14, the right-hand end of the member thereby being forced against the end 11 of the dolly 10 in both positions. In a modification, Fig. 4 (not shown), the spring is arranged between the fixed contacts and the dolly 10, but on the opposite side of the member 12, the point 14 being arranged at the opposite end of the member 12 to the contacts 13, and on the same side as the spring. In a further modification, Fig. 5, the member 12 pivots about one or other of two pairs of fixed contacts 13c, 13d.
