The PSE M22R illuminated piezo switch is a vandal-protected device said to be ideal for use in tight spaces. Actuating areas are illuminated, making the switches ideal for equipment designed for nighttime use. The ring illumination can also be used for optical feedback or for status “on/off” displays. With a 20-mil life cycle operation, the switch is said to require little servicing. Unlike mechanical switches, piezo switches have no moving parts, offering the advantage that even under continuous operation, there is less risk of parts wearing out. Schurter GmbH
