Float switch can not directly control solenoid valves or power relays, exchanges and contacts and the like. To add a small relay (eg HH54P) transition.Float level switch is a simple structure, easy to use level control device, it is not necessary to provide power, no complicated circuit, it has a smaller volume than mechanical switches, long life and other advantages. In shape as long as the material selection is correct, and the nature of any liquid or pressure, temperature can be used, which in the shipbuilding industry, generating equipment, petrochemical, food industry, water treatment equipment, dyeing and finishing industry, hydraulic machinery, etc. have been widely application.Tired of guessing how much water or fuel is left in your tank you need this brand new liquid float switch, which is made of stainless steel.This small size, low-cost switch can be used in most liquid environments. It can also be easily converted from normally open to normally close by inverting the float.Specifications:Contact rating (Max): 50WSwitching voltage: 0-220VDC/ACBreakdown voltage(Max): 300VCarry current(Max): 1.5AContract resistance(Max): 100mOhmTemperature rating: -10 - +120CelsiusMax. pressure: 1MPaCable length: approx. 35cmStick length: 150mmMounting hole: M10Material:stainless steelColor: SilverNet Weight: 2.42oz Package Contents:1 x Float Switch Stainless SteelNote: Light and different displays may cause the color of the item in the picture a little different from the real thing.
