Float switch can not directly control solenoid valves or relays, exchanges and contacts and the like. To add a small relay (eg HH54P) transition. Float level switch is a simple structure, easy to level control device, it is not necessary to , no complicated circuit, it has a smaller volume than mechanical switches, long life and other advantages. In shape as long as the material is , 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 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 liquid environments. It can also be easily converted from normally open to normally by inverting the float.
