Cap Touch click is a capacitive touch sensing button, integrated on a click board™. It can be activated by touch. This click can sense touch even through plastic, wood, or other dielectric materials, which can be used to protect the surface of the PCB and the sensor pad trace itself. Unlike the mechanical button, the capacitive touch button lasts much longer, it is not prone to damage and wear over time and it is very reliable.

Capacitive buttons are a very popular method of powering up various devices. Besides the aforementioned benefits, having a touch sensitive button on a device allows for a compact design, opens possibilities for various kinds of human-machine interface and - it looks good and modern, especially if accompanied by a LED that turns on when activated, just like the one on Cap Touch click. Cap Touch click can find its place among many applications - for touch activated lighting controls, touch activated control panels, toys and any other applications that need a switch or a button.

TouchKey 3 click is equipped with advanced capacitive sensors, based on the proprietary QTouch® technology, that can be used to sense touch on 7 different keys. Besides quite a large number of QTouch® capacitive sensing channels, it also offers some additional advanced features, such as the Adjacent Key Suppression (AKS®), a technology that ensures correct button press, even when the touch sensing pads are placed close to each other.

With its many sensing channels and their advanced sensing technologies, TouchKey 3 really stands out from the crowd. It can be used as a multi-button control pad for various embedded applications, replacing mechanical buttons, which are typically prone to malfunctions, with elegant and durable touch sensing pads. Since it can detect touch through 5mm thick layer of plastic, TouchKey 3 is covered with a protective plastic coating, which makes the click board™ even more robust and wear-proof.

Touch Key 4 click is a capacitive touch sensing Click board™, with the advanced touch/proximity sensor IC. It has three independently configurable channels and can work in several operating modes, including multiple button pattern detection mode, combo mode, press and hold detection mode, power button mode, and more. Capacitive touch sensor inputs are protected from false detection, which can be caused by the noise and RF interferences, providing a very reliable touch sensing functionality. Electrostatic Discharge (ESD) protection up to 8kV ensures that no ESD failures will ever occur while interacting with the sensor surface.
