ABSTRACT:
A single-pole single-throw electric switch having a fewer number of simple parts more easily adapted for automatic assembly, and having a low base height due to a leaf spring biased roller contact actuated by a double-incline apex on the operating lever movable overcenter on the roller contact to snap it into or out of bridging engagement with a pair of stationary contacts. A single insulating plate held in vertical grooves in opposite walls of an open-top base retains in place a pair of press-in lead leaf-spring connectors and also supports the stationary contacts in place up against the cover, the terminal portions of which are retained by their opposite edges in spaced vertical grooves in opposite walls of a pair of terminal compartments in the base. The arrangement is such that all the parts can be lowered down into the base in predetermined order thereby affording automatic assembly. The switch is operable by any one of a number of different types of operating levers such as a toggle lever, a trigger, a slide button, a push-push button, or the like, provided the cover is suitably configured to accommodate the desired operating lever, and is adapted for use with any one of a number of different types of connectors such as push-in lead, screw terminal or solder lug.
