SKF pressure switches of the DSA series are inexpensive mechanical diaphragm pressure switches. The microswitch is designed as a changeover switch and can therefore be used as both a normally closed contact (NC) and a normally open contact (NO). They are available for rising and falling pressures from 1 to 30 bar and have non-adjustable increments.
Design
The pressure cell containing the membrane and the pressure plunger is assembled with the microswitch in a compact plastic housing. The housing contains mounting feet so that the pressure switch can be mounted in any position. The electrical contacts of the microswitch are gold-plated. The membrane is made of FKM (FPM). The pressure switch housing is made of glass fiber reinforced polyamide.
