This family of switches is the basis for many applications, combining small size with robust electrical characteristics packaged for severe environments with flexible mountings.
One of the greatest strengths of this switch is the “push-to-open” contact design. This means that the force of the flat spring is providing consistent closing force compared to other designs which use the bimetal disc to maintain closure of contacts. The available force for closing contacts using the disc is diminished as the snap-point is approached, increasing susceptibility to vibration and shock.
Aerospace thermal switch for commercial and military application combines small size with robust electrical characteristics, packaged for severe environments with flexible mountings.
The 500 Series switches are manufactured in a controlled environment with temperature set points tested by a computer to assure accuracy and uniformity. The discs are 100 percent tested prior to assembly – no sample testing allowed.
