Schurter announces piezo switch family, PSE HI, offering raised symbols, letters, and numbers in addition to various colors, or legend inscriptions. The robust switch provides high-impact resistance and long life. The switch surface is made of anodized aluminum, which can be pre-formed with raised symbols for long-term wear and excellent user haptics.

The aluminum surface of the PSE HI switches can be produced in various anodized colors. A variety of standard legends and/or raised symbols is offered to indicate the switch function. The raised symbols can be numbers, as well as characters from the Braille alphabet. These flexible design options make it possible to offer a wide variety of standard or custom options to meet individual design requirements.

The PSE HI piezo switch has an ingress protection class rating of IP67. The hermetic seal makes the switch ideal for use in areas that must be regularly cleaned or disinfected. Additionally, the switch offers a robust metal housing, well suited for use in harsh environments where there exists the potential for vandalism. The impact resistance, according to DIN EN 50102, is IK06.

The PSE HI piezo switch is rated 0.1 A at 42 V_AC/60 V_DC. The piezo switching element offers an exceptionally long service life of more than 20 million switching cycles. Typical applications requiring such robust switch performance include pedestrian cross walks, elevators, truck lifts, material-handling equipment, safety equipment, ticketing terminals, gas stations, food service equipment, and processing plants.
