Advantages
Langir piezoelectric switches are based on a solid-state output allowing for a very long life expectancy (more than 50 millions cycles), ideal for demanding applications where reliability is most important. The flat actuation surface is completely closed, preventing the intrusion of liquids or other contaminants, perfect for surface cleaning required in the medical and food-processing industries. High-performance sealing (IP68 and IP69K) is achieved due to the one-piece construction of the switch. No external power supply is required. The screw-machined metal housing construction and Langir’s vertical integration allow for the manufacture of a variety of shapes.

FAQs
What is a piezoelectric switch?
A piezoelectric switch is a type of switch that operates based on the piezoelectric effect. When pressure is applied, it generates a voltage that can be used to perform a function.
What’s the principle of the piezoelectric effect?
The principle of the piezoelectric effect is based on certain materials’ ability to generate an electric charge when subjected to mechanical stress, such as pressure or vibration. This effect is reversible, meaning that the same materials can also deform in response to an applied electric field.
What are some common applications of piezoelectric switches?
Piezoelectric switches are used in a wide variety of applications, from consumer electronics and industrial machinery to medical devices.
What are the benefits of using a piezoelectric switch?
Some of the key benefits of piezoelectric switches are their durability, versatility, and energy efficiency.
What is the future of piezo switches?
The future of piezoelectric switches is promising with technological advancements leading to even more efficient and versatile devices. The energy harvesting feature could also contribute to sustainability in electronics.
What materials exhibit the piezoelectric effect?
Some common materials that exhibit the piezoelectric effect include quartz, Rochelle salt, and various ceramics.
