Langir piezo push buttons 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.

Q1: What is a piezo push button?
A piezo push button is a type of tactile switch that is used to activate or control electronic devices or systems. It utilizes the piezoelectric effect, which is the ability of certain materials to generate an electrical charge in response to mechanical stress. Unlike traditional push buttons that rely on physical contacts, piezo push buttons generate electrical signals through the deformation of piezoelectric materials, such as quartz or ceramics.
Q2: What is the principle of the piezo electric buttons?
When pressure or force is applied to the surface of a piezo push button, the piezoelectric material inside deforms, creating a voltage difference between two conductive layers. This voltage variation is then detected by an electronic circuit, which translates it into a usable electrical signal. The absence of physical contacts in piezo push buttons contributes to their longevity and reliability, as there is no wearing out or degradation of mechanical parts over time.
Q3: Can they be used in outdoor applications?
Yes, piezo push buttons are suitable for outdoor applications as they are designed to withstand harsh weather conditions and provide excellent sealing against dust and water.
Q4: Are piezo switches suitable for high-temperature environments?
Piezo push buttons can withstand a wide range of temperatures, but their suitability for high-temperature environments depends on the specific model and its temperature rating. It is essential to choose a button designed for the intended temperature range.
Q5: Can they be customized with specific labels or symbols?
Yes, many manufacturers offer customization options for labeling and symbols on piezo push buttons. This allows you to tailor the buttons to your specific application or industry requirements.
Q6: Do piezo push buttons require any special wiring or power supply considerations?
Piezo push buttons generally operate on standard DC power supplies. However, it is crucial to follow the manufacturer’s specifications regarding voltage requirements and wiring connections to ensure proper functionality.
Q7: Can piezo push buttons be used in safety-critical applications?
Yes, piezo push buttons are often used in safety-critical applications due to their reliability, durability, and resistance to tampering. They can be found in control panels and emergency stop systems where immediate and accurate response is essential.
