A Indicating Pressure Switch is a form of switch that closes an electrical contact when a certain set pressure has been reached on its input.
It offers a dual advantage of Indication and Switching. The switch may be designed to make contact either on pressure rise or on pressure fall.
Because of their robust design, they are suitable for harsh environments and most corrosive media and meet stringent demands to bring the advantages of high accuracy, long term stability, and protection against water jets and dust on their moving parts.
