Switchmatic Electronic Pressure Switch

Switchmatic Electronic Pressure Switch

These are high quality, electronic pressure switches for controlling the start and stop of single phase electric pumps up to 3HP (2.2 kW) in conjunction with an expansion vessel. Switchmatic pressure switches have an integrated digital pressure gauge, and the cut in and out pressure can be easily set and adjusted through the user friendly control panel. 

Wiring is carried out identically to a conventional electromechanical switch. 

Switchmatic can operate as a differential pressure switch, as an inverted pressure switch, or just with maximum or minimum pressures.
