Off-On-Momentary on. Includes rubber cap for moisture resistance. For use as Off-Run-Start or as Off-Run-Glow plug where the start function is handled by a separate button. Some installations use individual dedicated buttons, one for start and one for glow plugs. In this case, this switch handles the Off-On function but the momentary function is not utilized. Complete with two keys.
