They’ll withstand the rain and moisture of being outdoors, continuing to function as intended without succumbing to damage. To demonstrate the usage of a matrix keypad, we’ll initialise it and read the button presses from the board’s Python REPL. It’s easy to use a matrix keypad with Python or CircuitPython and theAdafruit CircuitPython Matrix Keypad module. This module allows you to easily write Python code that reads the button presses from the keypad. In the diagram above, the pins 1-4 correspond to the columns while pins 5-8 correspond to rows. Determining if a particular button is pressed is done by programmatically changing the digital pins between input and output and reading pin state.
We also offer standalone medical keyboards, the keywi CleanBoard and keywi CleanBoard Mini, specifically for use in demanding medical environments where hygiene is paramount. We mainly do customized Interface products and provide samples according to your design.

In this case we are using pins 2-8, but any 8 digital pins can be used if they are redefined in the rowPins and colPins statements below. These keypads are an inexpensive and easy way to add a robust key entry system. For example, if the ‘8’ button is pressed, there will be a low resistance path between the R2 and C1 pins. If the MCU sets R2 as a LOW output and reads C1 as an input, it will see the LOW and know that the ‘8’ button was pressed.
Artwork on the keys can cover the entire face of the membrane keypad. Membrane keys are overlays with a contact material on the inside of the dome such as carbon ink or silver paste, which makes contact with the PCB when the dome is pressed down. This type of membrane keypad only allows for button count to be reduced. Until recently membrane keypad graphics were exclusively screen-printed in order to achieve the ink adhesion and flex life required of the product. But now the design freedom offered by digital printing can be applied in membrane keypad manufacture and the opportunities to enhance the perceived value of your product are almost limitless. Combining screen and digital printing offers the best of both worlds. While additionally, digital printing provides an environmental benefit through the elimination of solvents.

The other type called dome switch keyboard, which uses a dome with printed letters on top, sometimes they are printed on or laser stretched. This type of keyboard uses a rubber or a silicone keypad that comes with domes as the top membrane layer. When the domes being press down, they collapse, and the graphite under the dome will complete the circuit underneath the membrane pad, thereby sent signal of a key being pressed. With a mature design and production team, HuaiSong provide professional solutions.
In case of flexible membrane Keyboard, cost of the product will reduce as well. In order to provide customer with optimal solution, it is very crucial for us to know where and how the membrane switches will be used. The most common approach we prefer is when customer provides a graphic drawing or design and a description of how and where the customer plans to connect the membrane keypad at their site. Additional information required for designing your product is mentioned below. Keeping the track of latest development in this domain, we provide clients with Soft Membrane Keyboard. Used in electronic industry, the gold plated domes used membrane keyboard is easy to use and is known for its excellent functionality.

Usually, we also use silicone rubber keypad, commonly known as a rubber dome keyboard or rubber dome switches. Foundation provides custom membrane keyboard products, ranging from the sequentially numbered label and decal printing to precision graphic overlay and membrane switch components. It is an operating system, which integrates key function, indicator element, and instrument panel. Also, it’s called touch keyboard, because the keypad will generate a tactile response in use. It adopts an integral sealing construction combined with flat and multi-layers. As we all know, the structure seals tactile membrane switch, graphic overlay, mark, symbol display, and lining board together.
A membrane keyboard may not provide you with the same degree of experience if you are looking to use them for perfect gaming. Yet another prime reason that would make a huge difference in terms of gaming is the mechanical keyboard vs membrane response time. The response time on a mechanical keyboard is accurate and faster than that on a membrane keyboard. In case you are a casual computer user, you would not be able to differentiate between a mechanical and membrane keyboard. However, if you are a die-hard computer user, you will find that there is a huge difference between a mechanical keyboard and a membrane keyboard. In fact, if you are involved in a lot of gaming, you will definitely need to invest enough to get the right and the best type of keyboard. While there may be a small decrease in responsiveness, membrane keyboards have their own set of advantages. Let’s get down to business with the first type of keyboard called a membrane, it uses 3 different layers in it design, which are very flexible. The first layer is called the top membrane layer, under the top there is a conductive trace. Very little, if any, tactile feedback is felt when using such a keyboard.
This membrane switch keyboard is a new type of electronic component, integration of light, machine, and electricity. Furthermore, the appearance of this type of keyboard marks a fundamental change in the appearance and structure of printed electronic products. This type of switch can replace key buttons of the regular discrete component part to perform the tasks of the operating system more reliably.

Tactile switches will typically use a dome retainer in place of this layer. Key design is essential to the membrane keypads expression and functionality. The graphic design, embossing and integration of light combine to provide optimal marking of the buttons’ position. LED equipped backlit membrane switches by Hoffmann + Krippner are less than 3mm thick and provide a uniform, bright, long-lasting illumination. Optionally, we can achieve a full light separation between the keys and allow to separately illuminate each individual key. The use of bi-color or RGB LEDs also provides a virtually unlimited choice of colors. In combination with our GT technology, the lighting effect can be enhanced even further.
A closed-loop is created when it connects with the upper circuit layer or the dome switch due to pressure from the outside. This closed-loop causes the actuation of the desired switching effect. Made of polyester or polycarbonate, it can be screen printed or digitally printed to your specifications to tell users how and where to press. The overlay typically will have letters, symbols, and icons printed on to indicate where to press. Embossed domes may be designed under the icons for a more intuitive button interface.
