of a multi-function switch with the high security of the Medeco

demanding usage in aircraft, weapons, medical and industrial control
and instrumentation, as well as ground support electronic equipment.
The Medeco lock is designed to resist drilling, wrenching, picking, and
other forms of physical attack. In addition, this quality constructed
switch is designed with double “D” mounting, versatile master-keying
capability, restricted factory-registered key system, and, on request,
