Custom Membrane Switches

A speed function (slow/fast) controlling a crane, for example, requires two distinctly different switching functions. Hoffmann + Krippner has developed membrane switches with double contact functions specifically for such requirements. For example, the first switching level is activated at a pressure of around 7N, and the second level at about 13N. Many machines and work stations operate in low light conditions, which mandates internally illuminated membrane switches. An ingenious combination of side-LED and light diffusing panels improves upon electroluminescent film technology to offer extensive color options, low power consumption, flat design, and long lifespan.

These button pushes can easily be detected using 8 pins on an MCU. Software libraries take care of all the messy work as shown in our example below. The MCU monitors for key presses by setting a row or column as an output and setting the pins LOW one at a time. It then looks for a LOW logic level on one of the pins on the opposite axis. The keypad terminates in an 8-pin cable which has 4 row and 3 column pins. The row pins are on the left as you are looking at the front of the keypad and they have a dark strip near the connector to help identify them. The connector is a standard 2.54mm (0.1″) pitch 1×7 female header.

The matrix is resistive which means that when no button is pushed, none of the pins are electrically connected. When a button is pressed, the corresponding Row and Col pins have a resistance of approximately ohms between them. The membrane is a thin but rugged plastic with adhesive on the back. The protective liner can be left in place to keep the keypad mobile or it can be removed and the keypad permanently mounted if desired. Click hereto compare the membrane keypad on several stores and find the best price. The buttons themselves are simple switch like closures in these circuits. The keys are connected into a matrix, so for the 3×4 matrix keypads, you only need 7 microcontroller pins (3-columns and 4-rows) to scan through the pad. On the 4×4 matrix keypads, you only need 8 microcontroller pins (4-columns and 4-rows) to scan through the pad.

I suspect this is for some kind of check-keypad-present thing, so I shorted out those traces on the controller board. It is essential not to make a mistake in mapping out the matrix. Underneath it, you’ll find the matrix with the pads for buttons. Our membrane switches enjoy extended durability and exceptional working lifespan. During the screen printing process, we design positioning holes on the PET. While, in this process, we use a laser punch machine through the holes. As we all know, the role of positioning holes is to ensure the smooth going of later testing and lamination. Flexible membrane switch, rigid membrane switch, and raised membrane switch.

Considering the membrane keypad design at an early stage can reduce the total cost of the product. The first one is the flat-panel membrane keyboard and the second one is the full-travel membrane keyboard. A flat-panel membrane keyboard is most often found on appliances that include microwave ovens and photocopiers. The top layer has the labels printed on the front and there are conductive stripes that are printed on the back. The flat panel membrane keyboards do not produce noticeable feedback. They are mostly used in harsh environments where waterproofing or leak proofing is required. A membrane keyboard is a computer keyboard where the keys are not separately placed like any other keyboards. The membrane keyboard has pressure pads that only comprises of outlines and symbols that are printed on the flat and flexible surface.

Numerous functions of a touchscreen can be fulfilled by a membrane switch, but with far less circuitry and voltage requirements. For many applications, membrane switches are a giant leap forward. Place the screen printed product on the visual inspection station to check the circuit. So it can help inspectors to check the circuit layer of membrane keyboards. Of course, according to customer needs, we also use FPC or PCB board to design and manufacture this layer. In order to increase some display effects on user interfaces, we can add LED light and SMT components. Furthermore, the fiber optic can be used under the user interface to provide visual feedback.

The American Society for Testing and Materials has developed international standards for membrane switches. For example, they have developed methods in determining the tactile ratio, contact closure rating and the standards for the effective visual inspection of membrane switches. The history of the switch goes hand-in-hand with the invention of the electrical circuit. Alessandro Volta, who was the inventor of the battery, was unclear if he used a switch when he managed to generate a consistent flow of current from his voltaic pile in 1800. However, it was during the time when the electrical light was invented, when electrical circuits took the center stage.

Just a small vibration can provide enough tactile feedback in a membrane keypad to improve user accuracy and satisfaction. Silicon keypads support multiple printed and molded colors, spray, textures and graphic backlighting effects. These solutions provide a soft feel silicone rubber key-top hardness range from 30 to 90 shore A, and are flexible in size and shape to meet all customer design needs. Switch contact solutions range from low cost carbon pill printed on rubber pad to high performance co-molded gold pill . Mechanical keyboards are specifically built for gamers, and the tactile and auditory feedback offered by these keyboards should definitely make it a huge option.
