This technology and proper chose construction makes our products work for many years, even in tough climatic conditions. Metal domes– specially formed metal switching elements, mounted into a silver circuit. With pressing and “click” they cause short-circuit and switching given function. Membrane keypad called also the foil keypad – consisted of many layers of films, with different properties and functions, combined with adhesive overlays. The following covers the pinout for the various key pad products. Using the software may require the use of a computer or other device that must meet minimum system requirements. It is recommended that you familiarize yourself with the system requirements before making your purchase.
Membrane switches are user-equipment interface utilities that allow for the communication of commands from users to electronic devices. Not everyone wants a mechanical keyboard for gaming; a cheaper alternative has always been the membrane keyboard. This gaming keyboard from Corsair has three dynamic settings for backlighting. It is Keypad with Flexible tail with/without connector as per design and application. The keys are mounted on multi layers of punched flexible polymer sheets sandwiched together. Circuits are silk-screened with conductive silver ink on both the top and bottom membrane layers. Low cost, reliable keypads, alternative key-life exceeds 2-5 million keystrokes, also lighter than a PCB.
A membrane keypad with no embossing has a completely smooth surface. For keyboards with flat keys without embossing, it is often an advantage that the key provides the user with feedback when activated. With unlimited graphic design possibilities, customised membrane keypads and switches support both product expression and brand value of the overall solution. This innovative membrane switch material combines antimicrobial properties with a hard, durable surface. The antimicrobial protection is directly integrated into the hard-structured coating to ensure an even distribution of the antimicrobial agent across the entire overlay for the product’s service life. We use nanotechnology to create dirt-repelling overlays that protect against any kind of contamination and mechanical damage. The front foil of every Hoffmann + Krippner membrane switch is printed from the back side. The upper layer of the membrane switch, with its sandwich construction, offers effective protection and the overlay can be easily cleaned and disinfected. Double contact membrane switches offer enhanced security and maximum reliability through keys with two switch levels.

A non-tactile switch works the same as a tactile membrane switch. In a non-tactile switch, there isn’t a physical snap or indicator that the button has been pressed. It’s usually indicated through lights, sound, or reading on the instrument display. On a non-tactile switch, the bottom side of the overlay is connected to a conductive pad, or an upper circuit layer is printed with conductive traces. When the overlay is pressed down the conductive traces connect to the lower circuit layer which sends a signal to a printed circuit board. A membrane keyboard is typically three different layers that are stacked on one another and work together in order to execute the proper command. The top and bottom layers are both membrane layers, and the middle layer is a spacer layer that has holes where each key is labeled on the top layer.
