Capacitive Touch Switches

Capacitive Switch is a touch switch activated by detecting changes in capacitance. The human body is electrically conductive and carries a small electrical charge. When the human touches the switch surface, the electrical charge will be transferred from human skin to the switch. The electrical charge will then cause a change in capacitance of the switch. This capacitance change disturbs the existing electrical charge composed in the switch and changes its electricity flow. This is where and when the capacitive switches receive the signal to trigger or execute an action. People may wonder why human body carries a tiny electrical charge. This is due to the human body contains water or in other words our body is mostly made up of water, and water contains charged ions which make it a perfect conductor of electricity.

Capacitive touch switches are available at Lumex. These rugged electro touch switches feature capacitive sensing mechanism and allow users to activate device by a simple touch on the surface of the switch. Like using smartphones, capacitive touch functions can always make switching easy, simple, and fashionable!
