What is a capacitive switch and how does it work?
A metal-over-capacitive switch is a unique solution that allows the use of aluminum, steel, or other conductive materials in front of a capacitive switch or sensor. This can allow a product to maintain an all-metal look to it while still utilizing capacitive technologies that give the ability for very finite sensing options.
