How Does a Piezo Switch Work?
Piezo switches have become a popular alternative to traditional plastic, as well as membrane, switches in recent years. Defined by their piezoelectric mechanics, they are durable, long-lasting and available in custom designs. While piezo switches can open and close a circuit — just like all other electrical switches — they are unique in several ways

Piezo vs Capacitive Switches: What’s the Difference?
Switches are found in nearly all electronic devices. While some of them are mechanical, though, others are touch-based. Two of the most common types of touch-based switches include piezo and capacitive. They don’t feature moving parts like their mechanical counterparts. Like all touch-based switches, piezo and capacitive switches will open or close a circuit in response to physical contact with a finger or object.

Pros and Cons of Resistive Touch Switches
Have you heard of resistive touch switches? While not as popular as capacitive or piezo touch switches, they are still used in many devices. Resistive touch switches use a similar method of operation as resistive touchscreens. They contain two layers, each of which features electrodes, that are separated by air. When you press a button, the top layer will push into the button so that the electrodes may contact. This contact will complete the circuit so that the resistive touch switch registers your command.

Capacitance vs Resistive vs Piezo Touch Switches
Touch switches are found in everything from smartphones and tablets to lamps and machines. The term “touch switch” refers to any type of electrical switch that requires touch to operate. Most touchscreen interfaces feature multiple touches switched embedded within the display. While all touch switches serve the same basic function, there are some subtle nuances between the different types. The three primary types of touch switches include resistive, capacitance and piezo.

What’s the Best Backlighting for a Capacitive Switch?
Backlighting is commonly found in capacitive switches. It consists of lighting system that’s able to illuminate the keys or button legends from underneath. If you’re planning to use a capacitive switch in a dark environment — or any environment with poor lighting — you should consider choosing a capacitive switch with backlighting. There are different types of backlighting, however, some of which work better for capacitive switches than others. What’s the best backlighting for a capacitive switch exactly?
