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.

Material

You should consider the faceplate material when choosing a piezo switch. Most piezo switches are designed with a faceplate. The material used for the faceplate, though, may vary. There are stainless steel faceplates as well as aluminum and plastic faceplates. Alternatively, you can choose a piezo switch with a glass faceplate. Each faceplate material has its own pros and cons. Therefore, you should evaluate your applications to determine which faceplate material is best.

Don’t forget to consider the back panel material when choosing a Piezo switches . All Piezo switches have a back panel. Like with the faceplate, though, the material from which the back panel is made can vary. Piezo switches are available in metal or plastic back panels. Metal is obviously the strongest material of the two. With a metal back panel, piezo switches can withstand extreme environments without succumbing to damage. Plastic, on the other hand, is lighter and better protected against corrosion.

Display Technology

In addition to the faceplate material, you should consider the display technology when choosing a piezo switch. Piezo switches are available in many of the same display technologies as touchscreens. You can find them with a liquid-crystal display (LCD), for instance. LCDs are energy efficient, bright, long-lasting and capable of producing high-resolution images. You can also find piezo switches with an organic light-emitting display (OLED). OLEDs offer many of the same benefits as LCDs, but they don’t require a backlighting system.

In Conclusion

Piezo switches have become an increasingly popular alternative to traditional mechanical switches. They are known as “piezo switches” because they use a piezoelectric element to open and close a circuit. By considering the faceplate material, display technology, sensitivity settings and back panel material, you can choose the right piezo switch for your business’s needs.
