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.

Langir leverages precision screw-machining, premium raw materials, rigorous quality control, and a one-piece sealed housing design to achieve outstanding performance and resistance to contaminants, delivering a switch that exceeds 50 million cycles with excellent reliability in demanding applications.
