    Tips: How to connect water pump pressure switch?

    Generally, there are 4 terminals, and there are two connection methods:

    1. Use the plug connected to the wire, insert this end of the plug into socket A, and connect the end of the wire to the first and third terminals of the switch. Then connect the second and fourth terminals to socket B, and connect the power supply of the booster pump to socket B.
    2. Disconnect the power supply, connect one end of the power plug to No. 1 and No. 3 posts of the switch, and then connect No. 2 and No. 4 posts to the other end of the power cord.
    3. If the pressure switch has four wires, it is generally a pair of normally open points and a pair of normally closed points. It can only start the pump and keep pumping, indicating that the pressure switch has no action. Theoretically, it is because the action value is set too high and needs to be adjusted. Low. In addition, if the pipeline is not closed, the pressure cannot go up. To test its action, all valves must be closed.
