Piezo Switches for Hot and Ice-Cold Conditions
Piezo switches from SCHURTER have proved themselves optimal in meeting the demands for extremely long lifetime and for an operating surface that is seal-tight in order to prevent the access of dust and fluids. For the switches with an N.O. switching function, the operating temperature range has been extended to -40°C up to +85°C. This means that the piezo switches can now also be used in outside applications where extreme temperatures and temperature fluctuations may occur.
The switches contain no moving parts, have a robust metal housing made of anodized aluminum or stainless steel and are hermetically sealed. The lifetime (lifetime > 20 million switching cycles) is almost unlimited, as barely any material wear or mechanical fatigue arises. The piezo switches are resistant to dirt, sand, dust and water; they can neither freeze nor stick through contact with fluids.
The following mounting diameters are available as standard: 16, 19, 22, 24, 27 and 30 mm. Other mounting diameters, materials, colors and shapes are possible for adapting the switches to specific design requirements.
SCHURTER offers the piezo switch with point or ring illumination from a mounting diameter of 22 mm. For devices with night design, the illumination serves to make the actuating surface visible. The ring illumination may also be used for providing optical feedback or for displaying the switch position (ON/OFF).
For lettering the actuating surface on our in-house laser-lettering unit, numerous standard lettering possibilities are available. Customer-specific lettering and symbols can also be produced.
