These switches are resistant to shocks and vibrations so any moving device can perform normally without breaking the facility of the switch. The designs now also allows the addition of electronic components into the flexible switch substrate so it can adapt to some special attributes needed for a specific control panel system. Compared to the most common switches we see at home — the light switch, membrane switches are operated by generating a finger tip force in the keys within its panel. Often used with microprocessor based control systems, membrane switches have become an essential part of modern instrument, machine and appliance panels that have specialized functions in our daily lives. Using a membrane keypad can mean the switch circuit moves from the interior of the product to the outer surface. In the same way leds can be shifted from a PCB inside the device to the membrane keypad .

These keypads are used in the ultrasound probe, medical device, industrial equipment, manufacturing equipment, aerospace industry etc. Silicone rubber keypads have small carbon contacts on the underside of each key. When a key is pressed, it collapses and the carbon makes contact with the traces on the PCB forming an electrical connection. With no perforations required for the membranes to interact, membrane keypads are easy to clean, resistant to water damage and ultraviolet radiation, and devoid of crevices for contaminants to nest. Rigid Support Layer – This backmost layer offers support for free-standing membrane assemblies. A membrane keypad integrated into a larger product may not need this layer. A membrane keypad with flat keys can be designed with frame embossing to highlight parts of the key, or other elements on the surface. With an embossing, a frame can be created around the key, e.g. highlighting logo, symbols, numbers and braille to make the key’s location clear.

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.

Normally, keypads are designed with individual keys, each of which is a separate moving part. But membrane keypads take a step in a different direction by featuring pressure pads on which the key outlines and symbols are printed. This keypad has 4 buttons, and since every key has its own wire line, no matrix code is required – just treat these like every day switches. The membrane is soft and has a removable paper backing to expose a strong adhesive so you can stick this on an enclosure and feed the cable through a slot. We include a 5-pin extra-long header strip so you can plug this into a breadboard with ease. Quad industries offers a fully customized solution in the process of developing membrane keypads and switches.

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.

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.
