Perhaps the easiest way to explain the function of a float switch is to look at their use within a toilet tank. This is a very important part of the toilet as it dictates the flow of water between the tank and the bowl. The tank will fill with water until the float reaches a certain level, the water flow will then stop until the toilet is flushed again and the tank empties lowering the float. As you can tell, this repeated use calls for a very durable product. This is why float switches are so coveted for the purpose they serve as opposed to an alternative they are incredibly durable.

If you are interested in a float switch for your application, but you aren't quite sure of what style is best for you. Consult a knowledgeable float switch manufacturer who will be able to walk you through the ins and outs of float switches. They serve a number of different purposes from activating pumps, drains, warning lights and sirens to a wide range of other uses and applications. There are a number of different designs for float switches such as metallic floats, plastic floats and a number of other materials. This housing unit for the float is also variable depending on the work environment your float switch will be placed.
