What is a level switch?

Level switches, or float switches, are used to trigger an opening or closing mechanism depending on a certain level of fluid within a chamber. For example, a level switch may be used inside a boiler or cistern, to ascertain a suitable amount of water is present before allowing the valve to be activated.

How do level switches work?

While there are various styles of level switch, most function in a similar fashion. The fluid inside a container lifts an attached float (either internal or external), activating a mechanical action that completes a circuit. This might be a mercury switch on a hinge, or a buoyant rod that rises to trigger a microswitch.

Level switches can be used for continuous or point measurements, and are often used in sequence. For example, a set of sensors climbing the wall of a tank can be used to measure continuous fluid levels, and trigger set actions at each new depth. Inside a shower pump system, the “on” sensor may be significantly higher than the “off” point, so that the tank will not be excessively filled or drained.
