25mm Piezo Switch
These piezoelectric sensor switches are part of the PZ series including models with dia. 12, 16, 19, 22, 25 or 30mm bushing. Sealed to IP68 or IP69K, easy to clean metal surface, long life (50 million cycles), ring illumination, custom configurations. -
30mm Piezo Switch
30mm panel cutouts Long life (50 million cycles) Easy to clean metal surface Ring or Dot illumination options available Latching or Momentary function options available Sealed to IP68 or IP69K (switches mounted on panel) -
Independently Operated Piezo Switch
Independently operated piezo 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. -

Why Choose Langir Piezo Switches?
Inside a piezo switch there is nothing to break: pressing the face flexes a piezoelectric element that generates its own switching pulse — a solid-state action rated beyond 50 million operations. With no plunger, spring, or contact gap, the one-piece metal front seals to IP68/IP69K, surviving submersion, pressure washing, ice, and grime that destroy mechanical switches. The PZ Series spans 12mm to 30mm bushings, plus independently operated and plastic-bodied variants. For medical, food-processing, marine, and outdoor public equipment, piezo is the switch that treats abuse as routine.
Frequently Asked Questions About Piezo Switches
Technology explanations and selection help for the PZ Series piezo range.
Pressing the switch face strains a piezoelectric crystal, which generates a voltage pulse that the switch electronics convert into a clean output signal — all with zero mechanical contacts.
Over 50 million activations, since no component physically wears. Many installations outlive the equipment they were fitted to.
The switch withstands high-pressure, high-temperature washdown jets — the standard demanded by food processing and hygienic equipment cleaning regimes.
PZ Series bushings from 12mm through 30mm, an independently operated version with isolated solid-state output, and a plastic-bodied variant for cost-sensitive or non-metallic designs.
Yes — actuation depends on pressure, not skin contact, so heavy work gloves operate them reliably, unlike capacitive alternatives.
