РусскийPA04 Air Pressure Switch
The air pressure switch is a pressure-operated electric switch for use in regulating the tank pressure between two preset values on electrically driven air compressors. The air pressure switch is available with an unloader valve, which prevents compressors from starting under load, and an On-Off button for manual cut off the compressor. A four port manifold style is available which provides a means for easy mounting of valves and gauges.
