The pressure switch is designed to control the switching on and off of the compressor depending on the pressure in the receiver. Screws into the port of the receiver or valve block, as well as into any “gap” inlet pneumatic line. For a set of two compressors, one pressure switch is sufficient. The pressure relay is low-current, it can only be used in conjunction with a power relay. The pressure relay must turn on the power relay, and the power one must turn on the compressor.
Range 1-8 bar = 15-120 PSI
