Schurter's new ring illuminated piezo switch, the PSE M22R, is a vandal protected device ideal for use in tight spaces. As the actuating areas are illuminated, they are ideal for equipment designed for nighttime use. The ring illumination can also be used for optical feedback or for status display (On/Off).
With a 20 million life cycle operation, the switch requires little servicing. Unlike mechanical switches, piezo switches have no moving parts, so even under continuous operation, there is no risk of loss of function due to parts wearing out.
The switches are completely sealed by design and all the electronics are encapsulated inside the housing. The switches are rated to IP67 specifications and an O-ring is supplied to seal the front plate. With a mounting diameter of only 22 mm, the PSE M22R is the smallest piezo switch in the company's ring illuminated product line.
The housing is made of anodised aluminium and is available in various colours. The ring illumination is available in red and green and also 2-colour red/green. Connection of the switch is either via wire or, alternatively, via a Molex type connector.
The socket features a D-shaped area to allow for the correct positioning of marked switches. Various standard type fonts are available for the marking of the switches on the in-house laser marking machine. Customer specific type fonts and symbols can also be marked.
