Abstract

443,748. Tumbler switches. BAIN, R., 25, Beaudesert Road, Handsworth, Birming- ham, and ALLDAY, N., The Nest, Streetly Lane, Four Oaks, Warwickshire. Sept. 4, 1934, No. 1461/35, Divided out of 424,434. [Class 38 (v)] A tumbler switch has a dolly comprising an insulating part 20 moulded on to a stud 21 riveted to a U- shaped stirrup 22 formed at its lower ends with holes 23 for pivotal engagement with outwardly directed lugs 25 on a U-shaped depending portion 24 of a metal bridge piece 9. A movable contact-member 12 comprises extended contact pieces 14 and a central U-shaped portion 13 extending on either side of the arms of the dolly to which it is pivoted by means of lugs 26. A snap-action spring 29 is in compression between a struck up part 28 of the base of the central portion of the contactmember 9 and a shoulder on a link 30 which slidably engages the part 28 and has a forked upper end 32 engaging a cross-bar in an aperture in the U-shaped stirrup 24 of the bridge. The movable contacts 14 engage fixed contacts arranged on the outer sides of upstanding walls on a base (not shown) on which the mechanism is mounted by means of the bridge 9.
