A capacitive switch is a touch-controlled electrical switch that only requires a small amount of pressure from an object to operate. The device uses the simplest kind of touch sensor technology as they are an on/off electronic switch that is only on when some pressure put on it. Capacitive switches are used once mounted to a touchscreen panel and allow you to have a few switches for the application that you require. These switches will work when mounted behind the surface of either glass, acrylic, or plastic panels allowing you to design your panel how you like with high brightness LED lighting for each switch.
RS offer a wide range of high-quality capacitive switches from industry-leading brands including APEM, Bulgin, Schurter, and of course RS PRO.
As these switches are mounted on the rear of the panel, they are tamper-proof and can be wiped clean making them perfect for a range of applications such as:
Capacitive switches can be programmed to a high, medium, and low sensitivity depending on the application they are being used in.
