Which Level Switch Is Right For You

A level switch is a device that changes the voltage of an electric circuit. There are many different types of switches, and they come in all shapes and sizes. LKI AS will guide you through all of those types.

Manual on/off switches are very simple. They have two common uses: in industrial machinery, and at the end of a water well pump to stop it from pumping when the process is complete. These switch types can be activated either manually by flipping an internal lever or pushing down on certain parts of the mechanism, or automatically through motion detectors that turn them off after detecting no movement over a period of time (this type is not used much anymore). Automatic level switches typically use mercury for their fluid levels; this chemical will expand according to temperature changes, which causes increased pressure inside the vessel where it sits if there’s too much liquid inside. This increase in pressure then activates sensors within the device that sense whether more or less liquid should be allowed into the vessel.

Automatic on/off switches are slightly more complicated than manual ones, but they still have two common uses: in industrial machinery and at the end of a water well pump to stop it from pumping when the process is complete. These switch types can be activated either manually by flipping an internal lever or pushing down on certain parts of the mechanism, or automatically through motion detectors that turn them off after detecting no movement over a period of time (this type is not used much anymore). Automatic level switches typically use mercury for their fluid levels; this chemical will expand according to temperature changes, which causes increased pressure inside the vessel where it sits if there’s too much liquid inside. This increase in pressure then activates sensors within the device that sense whether more or less liquid should be allowed into the vessel.

Light-sensitive switches work by allowing light to enter a photoelectric cell, and then activating it when enough photons are collected inside. This type of switch is typically used for outdoor applications where there’s no physical access to an on/off switch (elevators, submersibles). These can either have one set position or two different settings depending on how much light enters the sensor. Two common examples are “daylight detectors” which monitor sunlight levels through windows in large buildings so lights don’t go off during business hours, and automatic streetlights along highways that will turn themselves off after detecting darkness at nightfall with sensors within the roadway.
