Piezo switch

30mm Piezo SwitchPiezo switch 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.
The screw-machined metal housing construction and LANGIR’s vertical integration allow for the manufacture of a variety of shapes.

Plastic Piezo switch

Plastic piezo switch uses a piezoelectric chip. The surface layer, that is, the part seen by the user, can print, cover or press out the required information. Plastic piezo wafer is inserted into a pressed insulating layer (sleeve), which is sandwiched between two conductive sheets that make up the switch contacts. It is supported by the last plate. Compared with resistive membrane switch, some advantages of plastic piezo switch are as follows: 1. Plastic piezo effect is the characteristic of some specific crystalline silicon materials, including natural quartz crystal and artificial ceramic materials. When mechanical pressure is applied to these materials, the lattice structure will produce voltage and charge directly proportional to the pressure. 2. Plastic piezo switches require almost negligible physical movement, usually between 1 μ m and 10 μ m, to generate usable switching voltage or charge. 3. It is the simple exertion of external force rather than physical movement that produces the output of switch element.

  • 30mm Piezo switch

    These piezo switch (PZ series) available with different bushing diameters(12~30mm), material and shapes. Sealed to IP68 or IP69K, easy to clean metal surface, long life (50 million cycles), ring or dot illumination, custom configurations. 30mm piezo switches are ideal to use and task piezoelectric glass plates. The combination of these two devices provides a waterproof solution for underwater diving lights or other products used in harsh environments. It can be directly connected to a piezoelectric glass plate to create a latching high-current switch for battery-powered devices. The piezoelectric switch is a momentary action device, even if it is pressed for a long time, it can only generate a maximum pulse of about 200-400 milliseconds.

  • Piezo Switch FAQ Guide

    In our FAQ guide, we will talk about the piezo switch and every imperative information that you need to know about it.

    From its definition, types, common applications, how it works, and more, you will learn everything about this special switch right here.

    More importantly, we will also tell why Langir is the best manufacturer when it comes to piezo switches.

    So, before you invest in them, take time in reading our guide first.

    1. What is the piezo switch?

    The piezo button relies on the piezoelectric effect that produces a short “on” state pulse and the duration of this pulse can vary depending on the amount of pressure applied.

    When pressed with higher pressure, higher and longer voltages are also produced.

    The pulse can be further extended or changed from the “on” state pulse to the “off” state pulse with the use of additional circuitry and a slipper.

    It also has a capacitor that is responsible for storing charge allowing it to prolong its battery life.

    Its dominant trait is that there are no moving parts that make it stand out from the traditional mechanical switches.

    Plus, it is completed sealed, making it resistant to damage or external elements.

    And because of these characteristics, there is zero possibility of wear and tear, therefore, prolonging its service life and guaranteeing millions of uses.

    1. Does Langir customize piezoelectric switches?

    Customizing them or any other switch relies on the manufacturer’s capability.

    The type of customization also depends on its availability.

    It’s best to reach out to your manufacturer and ask if they can customize your orders and inquire what type of customizations are available for you.

    Langir could supply you with different customization as long as you send us your idea.

    1. Is Langir’s piezo switch waterproof?

    Yes, the Langir’s piezo light switch can be waterproof and the way to confirm this is to check its IP rating.

    If a switch is rated IP65, it is considered water resistant but not waterproof.

    But to confirm if it is high waterproof, it has to bear the rating of IP68 or IP69K and this means that it is dust tight too but this time, it can protect itself from close-range, powerful, high temperature water jets.

    So, if you require one for an application where there are risks of powerful water ingress, you should look for one that has an IP69K rating.

    1. Is Langir’s piezo switch vandal proof?

    Yes, piezo touch switch is strongly built to withstand frequent and even abusive use.

    Especially because Langir has engineered and manufactures rugged and durable products and these qualities have allowed some of the switches to pass the IK10 seal.

    The IK10 seal is a guarantee that the product is super vandal proof that can handle any kind of impact or up to 20 joules of impact.

    So, if you choose Langir, you are guaranteed that it is heavy-duty and can endure any level of use.
