In our Rod & Tube bimetal Thermal Switch products, contact movement is achieved via differences in the coefficients of expansion of two materials, in this case the outer tube and the inner rod. This family of switches is chracterized by very rapid response time and very high temperature sensing.
For ultra-high temperature switch applications, our X2 Series switches are our most popular option.
Used in helicopter engine exhaust, plastics extrusion, aircraft brake applications, among many other demanding applications for the industrial, aerospace, and military industries.
