How do pressure switches work
WebMechanical pressure switches are triggered using a spring and a piston to control the pressure at which they are activated. The spring is the force opposing the inlet pressure, and its tension is adjusted via a set screw or knob. In turn, the spring pretension is directly related to the pressure at which an electric contact occurs. WebJan 9, 2024 · Pressure switches rely on water pressure to do all the work.
