Abstract
204,667. Preston, W., and Walker, W. May 22, 1922. Switches, quick-action.-In a switch of the type described in Specification 204,357, wherein an operating member, a contact arm and a spring-controlled follower member are all capable of independent rotation about the same axis, the contact arm is restrained during the initial closing movement of the follower member by a relatively stationary element. A spindle a carries with lost motion a handle c and a sleeve f on which are insulatingly mounted the contact arms g. The sleeve f carries an arm i slotted at j, in which slot works a pin k on the follower member l, fixed to the spindle a and carrying a roller m, which co-operates with a cam n controlled by springs q to give the quick action. In closing, the arms g are restrained as by a spring r engagting the arm i or other appropriate part of the sleeve. Specification 207,363 also is referred to.
