Float switch is a simple, easy to use the level control device, it does not need to provide power, no complex circuit, it has a higher than normal mechanical switches, small volume and long lifetime. When used correctly as long as the material selection, fluid or pressure of any nature, the use of either temperature, and its shipbuilding industry, generating equipment, petrochemicals, food industry, water treatment equipment, dyeing and finishing, hydraulic machinery, have been widely application.

How it works:
Important from the liquid level sensor float reed switches and the composition of the float within the magnetic materials, work in confined non-magnetic metal pipe or plastic pipe set one or more magnetic reed switch, and then with a catheter through the one or more a magnetic material of the float, and double-loop control with fixed float and reed switch in the relevant position, float up or down with the liquid, use a magnet to attract the ball inside the reed at the beginning of the contacts, resulting in open and relevant action, for liquid level control or direction (when the float near the reed switch is conduction; leave switch off).
