Abstract
Abstract A toggle switch which has an operating lever extending through and pivoted in a threaded mounting barrel. In a longitudinal bore of the lever there is a compression spring and a plunger the latter being acted on by the spring and engaging a movable switch contact. The pivotal mounting of the lever comprises two ball bearings disposed at opposite sides of the lever and carried respectively in pairs of registered sockets and the lever and barrel, said sockets being external to the longitudinal bore of the lever whereby space is readily available in the bore for the plunger and spring.
