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.

Cap Touch 2 click is a capacitive touch sensing Click board™, with the advanced touch/proximity sensor IC, based on the proprietary RightSense® technology from Microchip. Cap Touch 2 click has six touch sensitive channels and six independent LED drivers with several operating modes, including touch sensor linking, as well as the pulsing and breathing effects. It also supports Multiple Touch Pattern Detection (MTPD), and press-and-hold function. Capacitive touch sensor inputs are protected from false detections, which can be caused by the low noise and RF interferences, providing a very reliable touch sensing functionality.

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.

Cap Extend 3 click features four capacitive sensor pads integrated on the PCB, that can sense touch through a variety of different materials. This click can sense touch through plastic, wood, or even metal, thanks to the proprietary Metal over Capacitive technology. All these materials can be used to protect the surface of the PCB and sensor pad traces, allowing implementation of all kinds of human-machine interfaces and seamless integration of the touch-sensitive buttons into various kinds of front panels. The click also features a connector used for connecting to external sensors.

Features like the multi-stage active noise suppression filtering, automatic environmental compensation, high signal-to-noise ratio (SNR) and support for a wide range of sensor pad shapes and sizes, allow this device to be used as a reliable replacement for buttons or switches in many applications, including light switches, office equipment and toys, display and keypad backlight activation, and similar applications where a reliable and aesthetically pleasing button alternative is required.

Cap Extend 4 click provides a unique opportunity to control digital devices by using a variety of physical objects. This click adds touch/proximity detection feature to any application, providing an easy and intuitive framework for building a human-machine interface. The click can be connected to eight different sensors, which can sense touch/proximity through a number of various materials, such as wood, plastic or even metal, thanks to Microchip's proprietary Metal over Capacitive technology.

Cap Extend 4 click can be used for building human-machine interfaces for various touch activated applications, such as light switches, toys and office equipment, device activation via the PCB touch buttons, and other innovative and interesting ways of touch control.
