S2 Series – Dual-Setpoint

CPI’s S2 switch is a variant of our M2 switches.

The S2 provides a two-temperature capability with one set (pins A and B) of contacts, opening on rising or falling temperature. The common contact then continues to move on rising/falling temperature until it makes connection with the contact for pin C at some higher/lower temperature. It is now possible to have a period during which no contact at all is made. A typical application would utilize the S2 to control a heater to warm a lube oil, then take no action as long as the oil maintains normal operating temperature. However, in the case of an overheat, the same switch could signal an overheat or initiate a cooling action.

Make The "Switch" to CPI

If your momentary switch application demands high performance, we think you should demand CPI. Please call us today to speak with our engineering team about your needs.
