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.

Piezo switch
Piezo switch

A piezo switch(sometimes referred to as Touch metal piezo switch) is an electrical switch based on the piezoelectric effect, designed to be installed in a location (or device) and application where they may be subject to vandalism or tampering, as in the case of pedestrian crossing switches, or fraudulent or unauthorized use, as in the case of vending machine switches. Anti vandal switch that are located on devices that are accessible to the public or which are located outside also have to be able to withstand dust, rain, snow, and frequent operation.

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?

5 Facts About Touch Switches

Electrical switches play an integral role in the function of countless electronic devices. From computers and smartphones to lamps, appliance, remote controls and more, many electronic devices feature one or more electrical switches. They are designed to open and close the circuit, thereby controlling the respective device.

Capacitive Switches: 5 Things You Need to Know

Not all switches use a mechanical method of operation. Some of them use electricity to determine when to open or close a circuit. Known as capacitive switches, they are commonly used in touchpads, proximity sensors and other switch-related applications. Below are five important things you need to know about capacitive switches.

An Introduction to Capacitive Switch: What You Should Know
An Introduction to Capacitive Switch: What You Should Know When researching some of the different types of electrical switches, you may come across capacitive switches. They’ve become an increasingly popular alternative to mechanical switches. You can find capacitive switches for consumer electronics as well as commercial electronics. Like all switches, they are designed to control [...]
Piezo Switches: An Introduction to These Touch Switches

Have you heard of piezo switches? They’ve become one of the most popular types of touch switches on the market. Like all touch switches, piezo switches don’t rely on moving parts to open and close their circuits. Rather, you can control them via touch. What are piezo switches exactly, and how do they work?

How to Choose a Capacitive Switch?

Are you looking to buy a capacitive switch? If so, you’ll need to choose the right type. Capacitive switches have become increasingly popular. Like all touch switches, they operate via touch. Capacitive switches use a similar method of operation as capacitive touchscreens, with both devices leveraging the human body’s conductivity properties to open and close their respective switches.

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

How to Choose a Piezo Switch?

Are you looking to buy a piezo switch? If so, you’ll need to choose the right type. While all piezo switches use a piezoelectric element to control an underlying circuit, not all of them are the same. They are available in different materials, technologies, features, design specifications and more. By following these tips, however, you can choose the right piezo switch for your business’s needs.
