Diaphragm pressure switches | Choosing the Right Pressure Switch
A mechanical pressure switch has two main components: the diaphragm and the piston. Diaphragm pressure switches operate by using the deformation of a diaphragm, which is subjected to the pressure being controlled on one side and the force exerted by a spring on the other side. To adjust the switching point of these pressure switches, the spring tension is adjusted. Diaphragm pressure switches can be used with pressures from 0.1 to 100 bar. Piston...
