When to use a Real Thermal Switch not a Sensor

When CPI started making thermal switches for the Military in the 40’s, there really wasn’t any other choice. Thermocouple based switches with variable set-points and various temperature ranges of operation were made using the thermocouple materials of the day, mostly copper, aluminum, and chrome. The concept of a thermocouple had been around for over 100 years but CPI switches of that time stood out because they provided reliable operation over an extended temperature range, in

Electromechanical Switch Endurance

If you're an engineer concerned about the reliability of your switch in a hostile, demanding operational environment, then you're worried about electromechanical switch endurance. In applications like limit switches, safety interlock switches, door open/close switches, and many others, failure of the switch can cause massive downtime, safety hazards, or damage to more expensive equipment that is not easily or cheaply replaced. Electromechanical switch endurance then refers to the ability of your
