Pressure switch

Products Mode: PA-104
pressure control switch for water pump

We have 2 different kinds of pressure switches, PA-103 and PA-104. They are mainly used for self-priming pumps.

A pressure switch is a mechanism that is designed to initiate an electrical connection when a certain amount of pressure is placed on it. A pressure switch is a form of switch that closes an electrical contact when a certain set pressure has been reached on its input. The pressure switch may be adjustable, by moving the contacts or adjusting tension in a counterbalance spring. The switch may be designed to make contact either on pressure rise or on pressure fall. Industrial pressure switches may have a calibrated scale and pointer to show the set point of the switch.
