Digital Capacitive Touch Switch Module


Digital Capacitive Touch Switch Module is based on TTP223B. Normally, it outputs low and keeps at a low power state. When a touch is sensed on the circular marked region, it outputs high and switches to the quick response state. When not being touched for 12 seconds, it switches to a low power state again. If the module is mounted on the surfaces of non-metallic materials such as plastic, glass, acrylic, you can make the keys hidden in the walls and desks.
