    Frequently Asked Questions

    The 12mm piezo push button switch uses piezoelectric technology that generates an electrical signal when pressing its metal actuator surface. Unlike traditional mechanical switches, it has no moving parts, providing a long-lasting, maintenance-free switching solution. Pressing the actuator deforms a piezoelectric crystal disc, creating a voltage that triggers a semiconductor switch, all enclosed in a sealed housing for durability.

    IP68 means the switch is completely dust-tight and can withstand continuous immersion in water. IP69K indicates it resists high-pressure, high-temperature water jets from multiple angles. Together, these ratings ensure the switch is ideal for wash-down environments, outdoor applications, and conditions requiring complete moisture and dust protection.

    Langir’s switch housings are primarily constructed from corrosion-resistant Stainless Steel 316L or Aluminum 6061 with an anodized finish. The one-piece sealed design, combined with O-ring sealing and specific potting materials, ensures robust protection against moisture, dust, and chemical exposure, meeting IP68/IP69K standards.

    Thanks to its solid-state piezoelectric design and lack of mechanical wear components, the switch exceeds 50 million actuations, making it suitable for heavy-use industrial applications requiring long-term reliability and minimal maintenance.

    No, the switch itself generates an electrical pulse upon pressing through the piezoelectric effect, which is enough to trigger integrated MOSFET or semiconductor circuitry. Other circuit elements (pull-up resistors or NPN/PNP outputs) might require external power, but the switch actuator itself is self-powered.

    Yes, with an actuation force between 3 to 5 Newtons and a smooth metal surface, this switch is designed to be reliably operated even with gloves on, supporting safe and convenient use in industrial, medical, and food-processing environments.

    The switch is available in soft momentary functions with SPST Normally Open (N.O.) or Normally Closed (N.C.) contacts, supports voltages from 1 to 24 V AC/DC, and carries switching currents up to 1A, making it compatible with low-power logic circuits and industrial control systems.

    Yes, Langir supports customization such as different actuator shapes (dome, flat, chamfer), illumination options (RGB LED with ring or dot pattern), wire terminations, connector types, and custom engraving on the actuator surface. Voltage and electrical customizations are also available.

    These switches are widely applied in medical devices, food and beverage processing, industrial automation, marine equipment, automotive controls, and outdoor systems, where waterproofing, durability, hygiene, and resistance to tough environments are critical.

    FAQs

    An illuminated push button switch is a device that combines a push button mechanism with built-in LED lighting. It provides visual feedback and improved visibility in low-light conditions. Key features may include momentary or latching operation, waterproof and dustproof sealing (IP65 or higher), long lifespan, and robust construction to withstand harsh environments.

    An anti-vandal switch is designed to withstand harsh environments and resist tampering or vandalism. It features a robust construction with a stainless steel or durable plastic body, a flush or raised actuator, and high resistance to impact and prying. Standard push button switches may lack these protective features.

    A momentary switch is a type of switch that is only active while it is being pressed or held down. It is commonly used for functions such as signaling, controlling relays, or activating a temporary operation until pressure is released.

    An IP65 rating indicates that the push button switch is protected against dust ingress and low-pressure water jets from any direction. This makes it suitable for use in environments where dust and moisture may be present.

    Yes, many illuminated push button switches offer customization options for the LED illumination, including color choices (red, green, blue, white, etc.) and different lighting patterns (ring, dot, or full illumination). Customization may also extend to the brightness levels and voltage configurations.

    Anti-vandal switches are commonly used in public access areas, industrial equipment, security systems, transportation controls, pedestrian crossings, elevator panels, self-service kiosks, and any application that requires a durable and tamper-resistant switching solution.

    Yes, momentary switches are designed for both indoor and outdoor use. However, for outdoor applications, it is important to select a switch with an adequate IP rating (e.g., IP65 or higher) to ensure protection against environmental factors such as dust and moisture.

    Yes, IP65 push button switches are designed to withstand wet environments. They are resistant to low-pressure water jets and dust ingress, making them suitable for outdoor use, marine applications, and areas where exposure to water may occur.

    Illuminated push button switches offer enhanced visibility, especially in low-light or dark environments. The illuminated indicator provides clear visual feedback, reducing the chance of user error and improving overall experience and safety.

    An anti-vandal illuminated push button switch provides reliable and tamper-resistant operation, making it an excellent choice for security system integration. Its robust construction prevents unauthorized tampering, while the illuminated feature ensures clear status indication for security monitoring.
