Installation Notes and Tips
Verify connector shape, terminal style, and plunger length before installation. Inspect the door jamb area for corrosion, bent terminals, or damaged wiring before connecting the new switch. Confirm proper switch alignment after mounting so the plunger contacts the door cleanly and the electrical circuit changes state as the door opens and closes.
