Comparing Keypad Technologies: PCB, Graphic Overlay, and Capacitive Touch Keypads
Efficient electronic products rely heavily on the usability and efficiency of their keypads. Keypads are an integral part of many modern electronic devices, with some of the most common types including a printed circuit board (PCB) keypad, a graphic overlay , and a capacitive touch keypad . PCB Keypads: A PCB keypad is a keyboard where the pads and switches are all mounted on a single circuit board. Each keypress completes a circuit and sends a signal to the device's controller. The many benefits of PCB keypads include low prices, long lifespans, and customization. Graphic Overlays: A graphic overlay is a thin, flexible sheets that are placed over the keypad to create a visual and tactile interface. The user experience can be improved by personalizing graphic overlays with their own designs, colours, and textures. Remote controls, video game controllers, and even medical devices all make use of graphical overlays. Capacitive Touch Keypads: Capacitive touch keypad is ...
