The membrane switch: Now for a different kind of panel that enables us to control the machines. It’s almost like a magic button that we press, and all of these things happen.
There are multiple layers in membrane switches. A graphic overlay The top layer is referred to a graphic overlay. The middle layer is printed circuit and the bottom layer is membrane. When we push a button on the graphic overlay, it contacts the printed circuit beneath. This is a signal to the machine that you need to do something. It is like whispering a secret to the machine!
Membrane switches can be found in places great and small, such as hospitals, cars and homes. They are used in hospitals by doctors and nurses to operate medical gear. Pilots and drivers in cars and airplanes use them to navigate and communicate. We also use membrane switches on stuff like microwaves and remote controls. They are everywhere!
Should you require a membrane switch that you can use for a particular machine, you can also design you won panels. First, consider how many buttons you want and where they should be positioned. Then you work with a company to make a custom graphic overlay with the perfect colors and labels. Once the design is finalized the custom membrane switch panel is designed specifically for you!
Membrane switches are great because they’re easy to press and simple to get. Buttons are flat and depress well with smooth touch. The graphic overlays may be constructed to perceptually enhance the visual discriminability of the graphic overlays by forming the graphic overlays with colors, pictographs, numbers, or text. They’re also strong and will not break as easily over the long term. They are ideal for machinery requiring both simplification and safety.
Technology is never still and neither are membrane switches! New additions include backlighting, touchscreens and tactile feedback. Button lighting is available when backlit. Touchscreens become capable of more complex interactions, while tactile feedback imparts a physical response when a button is pushed. These new abilities only add to make membrane switches more and more useful and fun to use.
