The surface texture of the membrane keypad can be gloss or matte-velvet. Protection by design- through the design of membrane switches can achieve antibacterial, anti-ultraviolet and other effects. Medical equipment and laboratory instrumentation manufacturers find membrane switch panels invaluable due to their resistance to contamination and ease of cleaning. Hybrid membrane switch/rubber keypad solutions can be engineered to meet even the most unique product requirements. Does the switch need to be able to withstand harsh chemicals and cleaning agents? Graphic overlays that are designed at BTI can be made with extra durable materials and seals to keep the device safe from chemicals. A membrane switch offers numerous advantages over a tradition mechanical switch. Overlay Adhesive – Usually made from a pressure-sensitive adhesive, this layer bonds the graphic overlay to the next layer. The circuit can then be actuated by pressure from the upper layer, printed with ink to indicate where to touch.
These assemblies have three parts, the electrical switch , the plastic locking nut , and the button . Rubber keypads provide a weather-resistant interface, and they are capable of withstanding exposure to moisture, dust, vibration, and shock. This makes them ideal for demanding environments and rugged applications. At PrintApp we can create circuit and front facia design out of almost anything including films, drawings, paper design or the keyboard itself. We have developed a systematic process to make sure that the features of the keyboard are double checked and replicated without error. With the consolidation of the field of Membrane Switches, many of our customers find themselves needing to order boards but they don’t have the design of the board or the circuit or both. Their previous supplier may have gone out of business or the keyboard supplied by them is too much costly.

The classic membrane keypad consists of about eight layers – only the uppermost level, the “front membrane” (décor foil), is visible on the subsequent application. This front membrane is manufactured individually according to your specifications. In the middle of all these levels is the snap dome, the actual “heart” of the membrane keypad. The snap dome is responsible for the tactile response and of course also for ensuring that the function selected by the user is transferred to the electronics. A keyboard that tolerates dirt and spillage that would otherwise cause a regular keyboard to fail. Membrane keyboards use a flexible plastic sheet printed with the key pattern on top and electrically conductive ink on the underside. When a key is pressed, it pushes the top layer down through a spacer layer of holes and makes contact with the circuit at the bottom. Widely used in self-service applications, there may be little movement in the keys, and a beep or LED is often used for feedback. There are several industries that employ membrane switches in their devices. On common household appliances, the membrane switch can be found on washing machines and microwave ovens.
In general, different customers have different membrane keyboards demands. Always, their requirements include appearance, colors, sizes, tactile feel, functions, and so on. Then, we will synthesize these with our production equipment and economic cost. After the customer selected us, we designed and manufactured membrane keypads. Most QWERTY computer keyboards use a single rubber-like membrane underneath the keys that makes contact with a circuit board when the key is fully depressed. Also called a “dome switch keyboard,” this style is also found on many types of keypads.
Unlike the rubber membrane, the keyboard and the keys therein make use of a mechanism for the working. Membrane switches can be thought of as one category of interface utilities alongside touch screens, plastic keyboards, toggle switches and many other kinds of control systems. An easy-to-use membrane keyboard the LESHP is a wired multimedia keyboard. It is comfortable to use and very responsive, unlike most membrane keyboards. Sleek, lightweight, quiet, durable are few of the terms used to describe this versatile product. This HVER is a rugged well-built keyboard which even though being a membrane keyboard is a good match for the best mechanical keyboards.
What’s more, sometimes, the lower circuit layer may have terminals to connect the machine interfaces.

They can replace mechanical switches, save valuable PCB space, and are an easy one-piece, one-operation assembly. This type of keypad mounted on panel with help of adhesive layer on back side of keypad. These keypad it is the same like computer keyboard, but rather the pressure pads that have only outline symbol printed on a flat, flexible surface.
Attach the jog handle assembly to the control pendant enclosure with nuts. Use the upper right corner to align the keypad on the control pendant enclosure. To install the keypad, insert the 24-pin ribbon cable through the front opening of the control pendant panel. Carefully pull out the 24-pin ribbon cable through the front opening of the control pendant panel as you remove the keypad. Carefully disconnect the keypad’s 24-pin ribbon cable from the keyboard interface PCB. Once the tab is unlocked, pull the electrical connector off the button .
Doing this across all possible pin combinations is referred to as a scan. All of that work is typically taken care of for you in a library.

As you would have observed from the above discussion, both mechanical and membrane keyboards come with their own advantages and disadvantages. If you are on a budget and do not necessarily care for the performance of your keyboard, a membrane keyboard would be a good choice.
With a flat surface to work with, the sky is the limit for creativity and artistry in your product design. You may have held a dozen membrane switches and not even known it. A tiny, slim-profile plastic remote controller, keypad, or touchpad with buttons consisting of raised impressions in a sealed outer layer is almost certainly a membrane switch. They are convenient, inexpensive, and highly portable because membrane switches are so thin that it can be hard to imagine a device of any consequence built into such a slender chassis. Membrane keyboard offers a similar typing experience like a mechanical keyboard. The dome-switch keyboard makes use of rubber or silicone domes for stimulating the spring structure of the mechanical keyboard. This is what offers these keyboards with solid physical feedback. Here you are advised to provide a detailed circuit diagram of electronic components with component specifications including pin numbers of connector. However we recommend to provide us the freedom to select connector pin numbers so that we can minimize the cross connections and reduce the complexity and improve the reliability of the Keyboard.
