PRESSURE SWITCHES

These switches are designed to control the pressure of electrically driven Air Compressors and Water Pumps. Switch contacts activate when a preset range; opening on pressure rise and closing on pressure drop. Air Compressor switches are available for one way and for way valve configurations.
