We carry the Condor MDR3 series of pressure switches. The MDR3 series pressure switches are commonly used on air compressors, as well as water and engine technologies, agriculture, and mining and chemical industries. To get started, look on the bottom of your switch, does it have one opening or 4? Choose either 1-port or 4-port.

Don't worry about the long number on the switch, this is not the part number.
