Product Description

The Digital Sensor TTP223B Module Capacitive Touch Switch is based on a touch-sensing IC (TTP223B) capacitive touch switch module. Allows you to remove the worry of conventional push-type keys.
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 surfaces of non-metallic materials such as plastic, glass, acrylic, you can make the keys hidden in the walls and desks.
