Compressor Pressure Switch 105 to 135 psi

This Powermate pressure switch controls compressor operation between 105 and 135 psi. It features four ports for connecting supply lines, gauges or safety valves. The component fits Industrial Air, Porter Cable and Powermate branded compressors. A Proposition 65 warning applies to this part.

Four-port design simplifies plumbing

The four ports let builders route multiple connections without extra tees or manifolds. It replaces the original switch on compatible units and restores automatic cut-in and cut-out function. Buyers needing a different pressure range or fewer ports cannot use this model. Installation requires standard pipe-thread tools and thread sealant.

Questions about this item

At what pressure does the switch open the circuit under continuous cycling?

The switch opens at 135 psi, the upper limit of its 105 to 135 psi range, when the compressor reaches cut-out pressure during sustained operation.

How much heat does the switch body dissipate when the compressor runs all day?

The switch body is a compact brass housing with four ports; it dissipates minimal heat because the electrical contacts carry only the motor control circuit current.
