Metal Touch Sensor

Detects the change in capacitance when a person touches a metal contact, turning any conductive surface into a button with no moving parts. Used for touch-activated lamps, hidden switches behind a panel and interactive exhibits. Because there is nothing mechanical to wear out or let water in, it lasts far longer than a pushbutton in public or outdoor installations. Turns any metal surface into a touch button; No moving parts to wear out or jam; Digital output, no analogue processing; Works through thin non-conductive coatings
