Abstract
409,202. Tumbler switches. COOK, F. L., 42, Mollison Street, Abbotsford, Victoria, Australia. Sept. 27, 1933, No. 26603. Convention date, Nov. 16, 1932. [Class 38 (v).] A tumbler switch comprises a dolly 1 having integral arms 2 provided with studs 3 adapted to be sprung into recesses formed in the base. A contact arm 15 is pivoted in recesses 17 in the dolly and the lower part of the contact arm is connected by a tension spring 12 to a lug 11 on a bridge 8. Thus on rocking the dolly the upper end of the contact arm is carried past the dead centre position and snaps into engagement with fixed contacts 16. The sides 18 of the recess 17 in the dolly assist in giving a positive start to the contact arm 15. The spring 12 comes to rest against the bridge 8 thus making a relatively silent stop. In modifications the spring 12 is replaced by a compression spring, or the bridge 8 is made resilient and the spring is replaced by a rigid link.
