Pressure Switches

category image

General Air Products’ pressure switches (also used for vacuum and called a vacuum switch) consist of a switch mechanism that is connected to a bellows or diaphragm that reacts to system pressure.  They are selected by operating range and differential. Operating range is the pressure limits in which the switch will work.  Differential is the difference between the cut-in and cut-out pressures.  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 varies with the pressure range you’re actually working in.  As pressure increases, available differential increases as well.  Some switches have differentials as low as 5 PSI. The contact points in the switch are usually rated for the amount of current they can carry.  Use the charts below to begin the selection process to order the pressure switch that best fits your application, or contact us for assistance and bulk pricing!

69H Series Pressure Switches

The rugged 69H series pressure switch is designed for the demanding requirement of larger, heavy duty commercial air compressors (up to 250 psi). This style is available with an unloader valve option to prevent the compressor from starting under load. The most common 69H switches can be ordered online with or without the unloader option. If your pressure switch needs fall outside of the products shown here contact us for details on our complete pressure switch line.
