The Lefoo 120V AC 20A Air Compressor Pressure Switch LF10-L Single Port Black is a pressure-operated electric switch for use in regulating the tank pressure between two preset values on electrically driven air compressors. This Air Compressor Pressure Switch available with an unloader valve, which prevents compressors from starting under load, and an On-Off button for manual cut off the compressor. For pressure- and flow-control applications in air compressors with a non-return, non-rising needle valve or unloader valve. The gas valve is preset for the desired working pressure range. If the pressure rises above this range, the bimetallic disk is heated and the disk moves upwards, allowing contactor action to take place.
