The Paravion® Switch Lock is designed to prevent unauthorized access to aircraft in accordance with U.S. Forest Service and Office of Aircraft Services contracts. The Switch Lock can be installed in any circuit deemed to meet the lockout requirements.
During installation, the 4-number combination is set and can not be reset without completely uninstalling the box, preventing unauthorized combination changes. The use of a combination lock also eliminates the annoyance of lost keys, particularly when operating in the field. The housing is made of aluminum and weighs approximately 0.6 lbs. The Switch Lock kit is not intended for use on type certificated aircraft and is only produced at customer request.
