Keypads intended for outdoor use are susceptible to fading from sun exposure. The sun’s ultraviolet (UV) rays will beat down on the keypad, causing the outer graphics layer to gradually fade. This isn’t something that happens overnight. Rather, months of exposure to UV light will eventually cause the graphics layer to fade. In some cases,
Unless a computer has a touchscreen interface, it probably supports input through peripherals, the most  common of which is a keyboard. There are several different types of keyboards, including membrane, dome-switch, capacitive, mechanical-switch, buckling-spring, hall-effect, optical and more. Each type has its own unique characteristics. Keyboards used for computers, however, are often designed in a
Synaptics Inc., maker of computer hardware like display controllers, touchscreen interfaces, biometric sensors and more, has acquired the chipset maker Conexant System for approximately $300,000 million plus 726,000 shares of stock. This massive acquisition has led many analysts to believe that Synaptics is planning something big for the future – and according to a statement
Also known an elastomeric keypads, rubber keypads are characterized by their low profile and use of silicone-rubber materials. Unlike mechanical keypads, they use compression molding to create a webbing around the electrical switch. When you press down on the key, it allows the underlying switch  – which is usually made of a conductive metal –
Have you heard of PCB membrane switches? Short for “printed circuit board,” this style of membrane switch is characterized by the use of a switch that’s been printed or etched. Acid-resistant solder is applied over the PCB, and the remaining exposed areas are then etched away by applying acid. The solder protects the key components
A capacitive switch is a type of touch-controlled electrical switch that operates by measuring change in capacitance. It works in the same manner as a typical capacitive smartphone: when you touch the surface — assuming you aren’t wearing gloves — a small electrical charge is transferred from your body to the switch, which subsequently causes
Light-emitting diode (LED) has become a popular backlighting option for use in keypads, human machine interfaces (HMI), electronic displays and more. Consisting of a two-lead semiconductor with a p-n junction diode, it provides ample illumination when activated. While there are other backlighting options from which to choose, LEDs offer several key benefits when used in
Statistics show that more than 1.3 billion touchscreen devices were shipped in 2012. Since then, the number has only increased as more and more people seek the convenience and versatility of touch-controlled devices. However, whether it’s a tablet, smartphone, human machine interface (HMI), etc., all touchscreen devices should be ergonomically designed. To learn more about

What is a Membrane Touch Switch?

A membrane touch switch is a type of electrical switch that’s activated through touch and features at least one flexible substrate. Like other electrical switches, they are used to activate and deactivate circuits. Membrane touch switches are considered to be momentary because they return back to their original, default state when the user’s finger is
