Feature:1. Float switch has a long life and the switching frequency can reach 10 million times2. The automatic control switch of the bilge pump is ultrasonic welding to form a closed space, which is reliable and safe, and does not leak3. The switch can be removed from the base for easy cleaning, saving time and effort. Suitable for scenarios such as water conservancy engineering, hydraulic engineering, electronic engineering, etc4. The switch structure is simple and compact, easy to install and use, can avoid the useless power consumption of the pump, and extend the economy of the pump5. A device that makes use of the principles of gravity and buoyancy to switch on and off circuits or waterways. Floating switch that automatically controls the start and stop of the submersible pumpSpecification:Item Type: Float SwitchMaterial: ABSApplicable Voltage: DC 32V, DC 24V, DC 12V.Package List:1 x Float Switch1 x User ManualNote:1. Keep all wire connections above the highest water level. The wires should be sealed with waterproof marine sealant to prevent corrosion of the wires2. DC48V power supply can still be applied
