Feature: 1. This water pressure switch automatically turns on the pump when the pressure is lower than the switch set threshold, and automatically turns off the pump when the pressure exceeds the set threshold. 2. With the automatic pump switch controller, your water pump will have a flexible working with high working efficiency. 3. The pressure range is 0.8‑5.0 bar, and the pressure setting range is 1.4‑2.8 bar, and the adjustment is very easy as well. 4. Wide pressure range and pressure setting range ensures stable working under high pressure without seepage or leakage. 5. The whole pump control switch is made of zinc alloy and ABS material, which is corrosion resistant and very durable. Specification: Item Type: Water Pump Pressure Control Switch Material: Zinc Alloy + ABS Function: Mechanical switch pressure controller. Model: JSK-5 Rated Voltage: 220V AC Rated Current: 15A AC Maximum Working Pressure: 100000-500000 (Pa) Interface Thread: 1/4in Male Thread Pressure Range: 0.8-5.0bar Pressure Setting: 1.4-2.8bar. Package List: 1 x Water Pump Pressure Control Switch Note: 1. When installing this pressure controller, the connecting thread should be well sealed without leaking; otherwise, it may cause the motor to start and stop frequently and eventually burn out.2. The inlet and outlet must be fixed well to avoid damage to the wires.
