A long list of choices include differential pressure switches , explosion-proof pressure switches , NEMA 4 and NEMA 7 rated pressure switches as well as electronic pressure switches . A pressure sensor switch works by detecting when there is more air pressure in the ductwork, which is caused by the dryer exhaust moving through the ductwork.

Pressure switch settings, common to many air compressors, are set for a range of 40 to 250 PSI and an adjustable differential of 35 to 60 PSI. This means that the lowest pressure that the switch can be set to close at is 40 PSI, and the highest pressure it can be set to open at is 250 PSI. The differential that is actually available to use
