Feature: 1. [MAIN FUNCTION] The pressure switch is mainly used to adjust the pressure of the water pump, can set the adaptive pressure according to the working demand. 2. [DURABLE MATERIAL] The bottom of the switch is made of zinc alloy, which is corrosion resistant, can withstand high pressure without water seepage and leakage. 3. [SILVER CONTACT] The switch adopts silver double contact clutch, and the plane contact point is more stable to ensure the use strength of the switch. 4. [WORKING RANGE] The applicable pressure range of the switch is 1.8-2.6kgf/cm², the maximum current is 16A, suitable for more regulation scenarios. 5. [WIDE APPLICATION] The automatic pressure switch can be used for self priming pump, jet pump, garden pump and clean water pump, convenient and practical.
