An ultra high production snap acting switch includes a blanked sheet metal tab for providing extremely consistent and repeatable operation. The switch simply includes a sheet metal M-blade automatically spot welded (or riveted) to a sheet metal spring arm. The spring arm has an integral tab pressed between two flexible legs of the M-blade. The stress imparted by the tab accurately distorts the M-blade so that it assumes a very predictable bistable operation.
