Abstract
444,664. Tumbler switches. WAITE, R. T., Porthmeor, Bescott Road, Pleck, near Walsall. Dec. 29, 1934, No. 37251. [Class 38 (v)] The dolly 10 of a tumbler switch is pivoted at a point 13 that is below the pivotal axis 17 of the contact arms 14, thereby making the switch relatively shallow. The dolly 10 carries a U-shaped member 11 having slots in its legs which engage projections 13 on a fixed plate 7 and the contact arms 14 have projections at their upper ends that engage slots 9 in ears 8 that are bent up from the plate 7. A tension spring 15 connects the dollv and contact arms and holds them against their pivots. Positive actuation may be effected by pins on the member 11 engaging the contact blades.
