A float switch is a device that is mounted on the inside of a float, to put it in more simple terms it is a switch that activates when the float rises to a certain level. This can be used for a wide range of applications and is found in a number of different applications. Typically, a float switch is made from mercury and is activated once the float switch reaches a certain angle or level. Other times a float switch is simply just a float that is hooked up to a micro-switch with a rod that will flip a switch on or off depending on where the float is level wise.

Design of Float Switch
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.
