These fine quality switches are used in many aircraft. The switch housing is now machined from billet aluminum which makes this switch 25% lighter. They provide “ON” and “OFF” electrical control of both magnetos on single engine aircraft. The Key-operated switches mount from the rear of the panel in a 7/8” dia hole. Available with or without starter position.
With Starter Position. Supplied w/switch plate two keys. (diode included) A-510-2
