H50PS series pressure switch is
a miniature pressure switch. It controls the
circuit open or close on pressure of the
controlled medium increase or decrease. It is
widely used in powershift transmissions,
anti-skid braking systems, excavator hydraulic
systems, air compressor systems, and other
industry equipment requiring pressure
protection.
WORKING PRINCIPLE
H50PS pressure switch is an
apparatus, which can feel system pressure by
diaphragm, and transfer the pressure to spring,
push contacts of switch, then cut or close
circuit when pressure arriver set point. H50PS
series switch is specifically designed to stand
up to extended duty applications. The main
difference between H50PS and H20PS is: H50PS
series pressure switch is realized by compressed
spring, however contact operation of H20PS
pressure switch is arose by diaphragm flipping.
