Aerospace and defense customers rely on the Sensata KX Series sealed sine switch when freedom from environmental conditions is required.
The versatile Sensata | Klixon® sine switch element eliminates knife edges and high friction joints. It is sealed within a one-piece steel case with a metal "wave type" diaphragm at the actuating lever engineered to withstand high or low ambient pressures.
Typical uses on aircraft include door interlock systems, engine ignition, and thrust reverser indication.
