Capacitive Touch Switches & Panels

Capacitive sensing switch is a technology based on capacitive coupling which takes input as human body capacitance. This technology is used in keyboards also known by the name Capacitve Touch keyboard, capacitive sensing keyboard and feather touch Keys. These are capacitive sensors which use a change of capacitance on the capacitor pad. The working of capacitive switch keyboard is similar to that of a typical touch screen smartphone. When we touch the screen, a small electrical charge is transferred from our body to this switch. This causes a change in the capacitance. The switch then detects this change and responds with an appropriate command. Backlighting on the glass provides capacitive sensing keyboards a beautiful and aesthetically appealing appearance with strong graphic clarity. Capacitive touch control switches do not require the user to touch the metal directly as a printed glass is placed on the PCB which can eliminate potential safety hazard. As it has no mechanical components, it doesn’t wear out easily and has a long lifespan. Capsense keyboard can be used where hand-hygiene is important as these keyboards are also easy to clean using disinfectants and thus reduces the risk of cross contamination.
