Product designers can control a lot of the user interface requirements at the dome level. Requirements may include force, travel, audibility, or tactile feedback for your product. Other dome features designers should take into consideration are backlighting, built-in actuators, over-travel, and more. Membrane switches are critical electronic components in human-machine interfaces , especially those that need to withstand harsh environments.
They are reliable, effective, low-cost user interfaces, suitable for a wide range of products, and available with many creative options. For engineers of user interfaces for high-performance electronic applications – such as medical devices and rugged outdoor machinery – the membrane switch is often an afterthought in the overall design process. Providing the sole connection between the human user and machine, the membrane switch circuitry is separated from the outside elements by only a graphic overlay.
Because of this, you can view products but not place orders using Internet Explorer on our site. Regardless of which type you choose, they have surprising advantages over other HMIs and require custom converted tape to achieve those advantages. Tactile and Non-Tactile Options can be added, as well as Audio, Embossing, Backlighting, Back Panels and ESD/EMI Shielding. In this project when you press a key, it’s displayed the value in your serial montior. Here’s what you should see in your Arduino IDE serial monitor when you start pressing the keypad keys. If your keypad doesn’t work with code below you might have to change the connections from the previous schematics.
The primary role of backlighting is to highlight essential functions and illuminate the control panel in low light conditions. It also can be used for aesthetic purposes to enhance brand image and quality. We can offer the full range of backlighting options, including Light Guide Film , Light-Emitting Diodes , Acrylic Light Tiles and Electroluminescence . A user-interface assembly is a fully functioning turnkey input device integrating a variety of electronic components that connect the operator to the machine.

This has the advantage of shorter development time and a simpler circuit layout, which could affect switch cost. Membrane switches can be designed with a common bus or in a matrix. Matrix layouts are desirable for keyboards with many keys to simplify the interconnect.
Connections are made through conductive tracks on a connecting tail, and there are various styles of tail terminations available. For some applications, a hybrid design offers the best of both worlds. When a simple switch or sensor just won’t do, you can count on our advanced XyTouch technology to provide the flexibility of a touch screen and the accessibility and durability of fixed function keys.
