The Klixon KX Series hermetically sealed sine switch is a precision snap–acting device. It is designed for use in the aerospace industry and for other applications where operational freedom from environmental conditions is a requirement. (Performance chart.)

KX series switches are sealed within a one-piece steel case engineered to withstand extremely low or high ambient pressures. True hermetic sealing is achieved with a metal "wave type" diaphragm at the actuating lever. The actuating arm is keyed to hold the arm in alignment and to prevent damage to the diaphragm.

The switching element is the versatile Klixon sine switch. This simple, one-piece element eliminates knife edges and high friction joints. Rigidly supported at both ends and accurately prestressed in tension, the sine switch features outstanding resistance to shock and vibration.

Klixon KX series switches have been used in a variety of aircraft, weapons systems, aircraft engine and aerospace applications for well over 30 years. A brief listing of typical applications for the KX include:

Door interlock systems
Aircraft engine ignitions
Aircraft missle launcher position indication
External stores emergency jettison switches
Stowed / deployed indication for thrust reversers
Safety ignition indication for military jet engines
Radar pod door switches
Tank/armored personnel carrier missle launcher switches
Tank gun turret position indication
