Abstract

384,323. Tumbler switches. CRABTREE,.J. A., Endwood, Little Aston Park, Sutton Coldfield. March 3, 1931, Nos. 6536 and 6537. [Class 38 (v).] A tumbler switch of the type in which a tumbler lever h is connected to a contact-arm .d by means of a floating toggle-link f has an abutment'plate a having an aperture so shaped as to provide clearance for and positive start fulcra for the floating link f. The plate a is placed across a central well in the base and is secured bv vertical bolts which hold the ends' of the pivot pin d<1> of the tumbler h, and spacing washers (not shown) may be threaded on the bolts to adjust the height of the mechanism relative to the plate a. The floating link f has a narrow lower portion on which a compression spring f<4> is confined so that the upper part of the link may bear directly on tongues e in the aperture in the plate a, to give a positive start. The aperture is extended to form slots c<1> on each side of the tongues e to give clearance for the two sides of the contactarm, and the ends of the slots serve as stops for contact-arm. The height of the abutment plate may also be varied by having the ends of the plate stepped or cranked. Specifications 142,225 and 306,919, [both in Class 38 (v), Electric switches &c.], are referred to.
