Abstract

274,985. Tucker, J. B. May 13, 1926. Switches, quick-action.-In an electric switch of the tumbler type embodying a quick make and break action and means for efiecting a positive make and a positive break, the ordinary faces of the tumbler are arranged to make sliding contact with projections secured to or formed integral with the contact arm. In the construction shown the oscillating member b carrying the contact arm c is provided with inwardly turned extensions b<1> which are engaged by one or other of the lower faces of the tumbler a<1> to move the member b in the event of failure of the spring-controlled quick action. When the member b has been moved into the required position the abutment of the projections against one face of the tumbler forms a limiting stop for the member b.
