PS series pressure switch is a more advanced miniature pressure switch
in the world. It's one of the electrical switches that control the circuit
open or close on pressure of the controlled medium increase or decrease.
It's used widely in refrigeration system, oil pumps, air pumps, automobile
industries and others.
