Pressure switches
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 pump, air pump, automobile industries and others.
