Schurter PSE HI piezo switch

The PSE HI (high-impact) switch can be delivered with raised symbols, letters and numbers in addition to various colours or legend inscriptions. The switch surface is made of anodised aluminium, which can be preformed with raised symbols to provide good user haptics.

The laser-etched legends or preformed raised symbols enable long-term protection against wear. Raised symbols can be numbers as well as characters from the Braille alphabet. This makes it possible to offer a variety of options to meet individual design requirements.

The piezo switches have an ingress protection class rating of IP67. The hermetic seal makes the switches suitable for use in areas that must be regularly cleaned or disinfected. Additionally, the switches offer a robust metal housing for use in harsh environments where there exists the potential for vandalism. The impact resistance according to DIN EN 50102 is IK06.

The piezo switch is rated 0.1 A @ 42 VAC/60 VDC. The piezo switching element offers a long service life of more than 20 million switching cycles. Applications requiring robust switch performance include pedestrian-crossing walks, elevators, truck lifts, material-handling equipment, safety equipment, ticketing terminals, petrol stations, food-service equipment and processing plants.
