Float level switch (also named float switch) is consisted of a magnetic float, a stem with magnetic reed switch, the magnetic float moves with liquid level to actuate a hermetically sealed magnetic switch within the stem. The level switches are usually used for vessels having high-level or low-level alarms. Multi-point level switches can be designed according to customers' specifications.
Since technologies have become more and more advanced, the float level switch needs to be more safe, convenient and low cost. These float switches are extremely compact, simple and easy to install on any limited space, and will not be effected by electrical interference. They can withstand chemicals, high temperatures and pressures if the correct material of the float switch is selected.
