Capacitive touch switches work by measuring the change in capacitance of a PCB (printed-circuit-board) pattern depending on the placement of a user’s finger over a sensing pad. Capacitive switches are ...

Electromechanical switches are simple, cheap, and widely available (Fig. 1). However, they’re also plagued with a number of disadvantages, including wear with repeated use, and the potential for ...

Take a quick look at most older appliances, consumer products, and even medical devices of just a few decades ago and you’ll see their user front panels are covered with traditional, protruding ...

Capacitive touch technology has made tremendous inroads into a wide range of applications since its introduction to the market. Touch technology began with resistive touch screens used in the first ...
