What Are Light Guides and How Do They Work?

When researching backlighting technologies used in keypads, you may come across light guides. Light guides are often used in mechanical and membrane keypads. They don’t necessarily produce light. Rather, light guides distribute light across the keypad’s...
SAW vs Resistive: What’s the Difference?

SAW vs Resistive: What’s the Difference?

Capacitive might be the most common touchscreen technology, but there are technologies used to power tablets and other touchscreen devices. Some touchscreens, for instance, are powered by surface acoustic wave (SAW) technology, whereas others are powered by resistive...
How Does a PCB Membrane Switch Work?

How Does a PCB Membrane Switch Work?

Switches are used in most electrical devices. Consisting of a conductive path, they are designed to control a circuit. You can press or otherwise engage a switch to open or close the circuit. The electrical device will then respond with the appropriate action. There...
Infrared Grid (IR) vs Resistive Touchscreens

Infrared Grid (IR) vs Resistive Touchscreens

Infrared grid (IR) and resistive are two of the most common touchscreen technologies. They are used to power everything from tablet computers to human machine interfaces (HMIs) and more. While they both support touch commands, though, they aren’t the same. What...

When to Choose Resistive Touchscreens

Capacitive has taken over the touchscreen market. Even if you’re unfamiliar with the technology, you’ve probably used a capacitive touchscreen. Most smartphones, as well as many tables, use capacitive technology. There are also human machine interfaces...
