Abstract
435,284. Tumbler switches. PARSONS, Ltd., C. H., and HANDLEY, G. B., Wharfdale Road, Tyseley, Birmingham. June 4, 1934, No. 16528. [Class 38 (v)] An intermediate switch has a movable insulating contact-carrying block f pivoted by means of trunnions r on V-shaped arms s which have limited movement on a pin b on which is pivoted a dolly a which operates the contact block through a dead-centre spring toggle. The block carries two contacts g, h, Figs. 9, 10, each having three contact faces. The contact g is mounted on the upper surface of the block so that its contact faces g<1>, g<2> are on one side of the block and the contact face g<3> is on the other side of the block. The contact h is similarly mounted on the under surface of the block f. These contacts co-operate with two pairs of fixed contacts (not shown) mounted on the base of the switch, one pair on each side of the block f, and on being moved to one side or the other by the dolly a connect the fixed contacts in adjacent or diagonal pairs respectively.
