Stupidity at its finest! Drill the “lock hole” dead center of the switch plate. How is a lock going to go thru the handle of the toggle switch? Hole should have been drilled off center so a lock could be inserted through the holes and prevent movement of the toggle switch handle. Will have to weld the holes up and redrill the hole off center so it can be used for what it was designed for. Do mfg not THINK??
