Principle of Operation

Capacitance switches rely on electrical capacitance theory (the ability of a moderate to store electrical energy). When an electrical circuit has two separated conductive plates, the room between the plates acts as a capacitor and stores the electrical energy. Mediums have differing conductivity and dielectric constants which affects their energy ｓ storage capability. When the switch has connection with the medium, it may detect a change in the surroundings capacitance and this actuates the switch accordingly.

Materials with high conductivity or high dielectric constants such as water generally have high capacitance. The contrary applies for low conductive substances such as wax or air. Thus the switch is effective in mediums with reasonably high dielectric constants or conductive solutions.
