X2003 – Close-On-Rise (SPST), 1/2-20UNF-3A Thread

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.
