The PS series pressure switch is an advanced miniature pressure switch. It is an electrical switch that causes a circuit to open or close when the pressure of the controlled medium increases or decreases. It is widely used in refrigeration systems, oil pumps, air pumps, automobile industries and more. The mounting thread and electrical terminal can be selected according to the customer’s requirements. The micro-differential pressure switch, the temperature and pressure compound switch can be customized.
