The PSE HI piezo switches, manufactured by SCHURTER, are now available 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 pre-formed with variety of standard legends and/or raised symbols to indicate function. 

The laser etched legends or pre-formed raised symbols provide long-term protection against wear. Raised symbols can be numbers, as well as characters from the Braille alphabet, all of which improve user haptics.

The IP67 rated PSE HI piezo switches feature a hermetic seal, making them suitable for use in areas that need to be regularly cleaned or disinfected. Offered in a robust metal housing with an impact resistance of IK06 according to DIN EN 50102, the devices are suitable for harsh environments. Rated 0.1A at 42 VAC/60VDC, the switches have a service life of more than 20m switching cycles.

The PSE HI piezo switches are suitable for pedestrian crossing walks, elevators, truck lifts, material-handling equipment, safety equipment, ticketing terminals, gas stations, food service equipment and processing plants.
