Specifications: Product Name: Float Switch Max Switch Voltage: 100V DC Switching current(Max):0.5A Carry current(Max):1.5A Temperature rating:-10 - +120C Material :Stainless Steel Float Ball Size: 2.8 x 2.8cm (H*D) Screw Thread Diameter: M10 Body Total Length(L): 75mm Cable Length 38cm Color: Red, Silver Tone Weight :52g Package Content 1 x Float Switch Feature: 1. Float switch can be used in water tank, ponds, tanks, fish tank, and other liquid level control (drainage or water),do the upper and lower level alarm switch. Inside contacts are use reed switch sensitivity is very high. 2. Float ball point can not move in anywhere , the float point is fixed, up and down have circlip limit. 3. The circlip moving is not use, inside reed contacts are not moving. 4. Float switch can not directly control the pump or solenoid valve, float switch inside the reed contact current, control a large load will burn. 5. Control solenoid valves, alarms to add small relays, control water pump need to add a small relay and AC contactor. (According to the pump power equipped with the corresponding AC contactor). Description: This float switch is a simple structure,easy installation liquid level controller.It does not have a complex circuit,will not be disturbed,as long as the material selection,liquid,pressure or temperture can be used in any environment.Light weight and simple working principle,high reliability.
