About Level Switches
Level switches are used to detect liquid or powder levels, or interfaces between liquids. These level measurements are indicated via an electrical switching action. These are typically point level switches, measuring whether the level of a container has reached or gone over a predetermined point. However, switching mechanisms can be integral to continuous level switches as well. Multiple point switches can be integrated together to give a stepped version of continuous level. These level switches can be used either as an alarm device or as control switches, turning something on or off, such as a pump, or sending a signal to a valve actuator. What makes level switches special is that they have a switched output and can be either electromechanical or solid state, either normally open or normally closed.
The typical options for poles and throws are available. Most switches have either one or two poles and one or two throws, but some manufacturers will produce custom level switches for special applications.
