A large overtravel operating lever for a plunger (6) actuated miniature precision snap action switch (2) that includes a supporting bracket (8) having a cantilever strip (8c) extending over the plunger (6). A pivot (10) couples a lever arm (12) to the end of the cantilever strip above the plunger. A cam strip (16) is riveted to the lever arm (12) and extends between the plunger and the pivot and is formed with a nib (16c) for depressing the plunger and a constant radius contour (16b) leading from the nib for large overtravel of the lever arm. The cam strip (16) extends through a hole (8h) in the cantilever strip for clearance on movement and a stop (16e) abuts the latter to limit counterclockwise rotation of the lever arm to off position. A metal strip (18) riveted to the bracket extends across the plunger to prevent wear.
