Abstract
683,543. Tumbler switches. ASHLEY ACCESSORIES, Ltd., and EVERITT, L. H. R. Dec. 4, 1950 [Jan. 10, 1950], No. 582/50, Class 38 (v) A slow break switch, suitable for alternating currents, comprises a contact-member 13 pivoted on a knife edge 12, one end being acted on by a spring 14 and the other end carrying a contact 19 arranged to bridge contacts 16, the contact-member 13 having a leaf spring 24 secured thereto and engaging the dolly 22, in the "on" position, to take up any slack between the dolly and member 13 in this position. The contact 19 has a projection 21 seating in a recess 20 in member 13 so as to be self-aligning. Alternatively, it may be loosely connected to the member 13 by a rivet, and the member 13 may be loosely pivoted near its centre by trunnions engaging in holes in upstanding lugs, Fig. 4 (not shown). Specffication 667,462 is referred to.
