Product Description
Mechanical Diaphragm / Piston Pressure Switch
PS20 is mechanical pressure switch , the working principle and structure is built-in piston connected with precision springs, when pressure changes, the corresponding changes in the spring scale, when the pressure reached set value, can trigger preset mechanical structure and signal switch . Diaphragm and piston type pressure switches featuring the standard design are available off-the-shelf as break contacts, make contactsor changeover contacts, An adjustment screw makes it easy to adjust the switching point on-site.
Gold-plated contacts are also available as an option for small switching currents.
