Sub-miniature three position switch with built-in lever lock

Image Number 2 for United States Patent #4480159.

A toggle switch of sub-miniature dimensions eliminates the need for machining flat parts on the toggle lever or drilling a pin on the toggle lever by mounting a one piece lever lock insert within the upper portion of the cylindrical housing of the toggle lever, above the spherical portion of the lever, the insert having three aligned, generally truncated conical recesses in the top surface thereof, the larger openings being each adapted to selectively receive the generally circular, spring pressed detent on the end of the toggle handle and the smaller openings merging with the straight parallel side walls of a guide slot, equal in width to the diameter of the toggle lever, and also formed in the lever lock insert, none of the lever lock structure extending laterally beyond the externally threaded, generally cylindrical housing.
