Abstract

660,338. Snap-action switches. TELEPHONE MANUFACTURING CO., Ltd. Oct. 12, 1949 No. 26250/49. Class 38 (v). A tumbler switch comprises a resilient blade 4 fixed at one end 3 and the other end having integral therewith and secured thereto, two compression elements 15, 16, the free ends of which engage in V-notches 25, 26 formed in parts 20 of a dolly 19 pivoted at 21, 22, the blade passing through a space between parts 20. The thrust exerted by the compression elements retains the dolly in either position and when they are moved over-centre snap the contact 6 from one fixed contact 7 or 8 to -the other. The blade 4 is strengthened by a rib 31 and has projections 27, 28 engageable bv abutments formed by the sides of notches 29, 30 in the parts 20 so as to give increased contact pressure and positive actuation if welding of the contacts occurs. One of the contacts 7, 8 may be replaced by an insulating stop, and the switch may be of the single or double-pole type.
