Pressure Switch
Pressure switches open or close an electrical contact when pressure reaches a set point. They start and stop pumps and compressors, trigger alarms and shut equipment down when pressure is unsafe.
Pressure Switch Types
- Mechanical switches – simple, reliable and no power needed
- Electronic switches – adjustable set points and displays
- Differential pressure switches – filter and flow monitoring
- Vacuum switches – vacuum system control
- Explosion-proof switches – hazardous areas
Choosing a Switch
Select set point range, deadband, electrical rating and wetted materials. Fixed or adjustable deadband affects cycling. Add snubbers for pulsating systems.
Centro carries pressure switches for pumps, compressors and process safety.
