Over 80 years of combined U.S.-based application engineering experience enables us to deliver the highest level of service and communication to keep your project on schedule.
We mainly do customized Interface products and provide samples according to your design. We also offer standalone medical keyboards, the keywi CleanBoard and keywi CleanBoard Mini, specifically for use in demanding medical environments where hygiene is paramount. Determining if a particular button is pressed is done by programmatically changing the digital pins between input and output and reading pin state. In the diagram above, the pins 1-4 correspond to the columns while pins 5-8 correspond to rows.

This module allows you to easily write Python code that reads the button presses from the keypad. It’s easy to use a matrix keypad with Python or CircuitPython and theAdafruit CircuitPython Matrix Keypad module. To demonstrate the usage of a matrix keypad, we’ll initialise it and read the button presses from the board’s Python REPL. They’ll withstand the rain and moisture of being outdoors, continuing to function as intended without succumbing to damage. Of course, you can customize the structure members and services. So, HuaiSong only needs a shorter membrane keypads manufacturing cycle than our peers. Also, our engineers will follow the entire keypads keyboards producing process. In fact, as a membrane keypad manufacturer, all our products are cost-effective. HuaiSong membrane keyboard manufacturer pursues smaller and smaller error.
As a result, we do these to keep our membrane keypads constantly improving. From the very first, our production equipment has been under regular maintenance and inspection. With diverse production equipment, we build mature and suitable membrane switches. These membrane keyboard, which work by electrical contact between the key surface under layer circuit when key areas are press.
