Multicolored Illuminated Piezo Switch Family for SCHURTER PSE - 1

Application Note Multicolored Illuminated Piezo Switch Family for SCHURTER PSE SCHURTER expands its successful PSE range of piezo metal line button style switches with multicolored illumination Today, SCHURTER's piezo switches are used in many applications, especially in harsh environments. The advantages of using a piezo switch are many, but one of the key benefits is their completely sealed surface, which can be activated by applying minimal force to signal actuation. These switches are now offered with a new multicolored illumination. absolutely impervious to leaks. Unlike pushbuttons with a mechanical stroke, no dirt can accumulate underneath or around the switch. This technology is ideal for hygienerelated applications such as those in medical, the food processing sector and outdoor applications. The pulse derived from the force exerts pressure on the piezoelement, thereby converting the physical pressure into an electrical potential. This pressure is sufficient to produce a clear, potential-free signal, which is possible with the employed semiconductor components. Because of the sealed surface, the product has IP69K seal and thus is The new multicolored illumination of the PSE series greatly expands its application range. The round button style switch is available with 22 mm, 24 mm, 27 mm and 30 mm diameters. To make the integration into customer specific applications as easy as possible, the strands are color-coded in each of the illumination colors and are supplied with a voltage range of 5 to 28 VDC providing a brightness that remains constant in all applications. The standard version is offered in red, green, and blue. Additional color options include yellow, cyan, magenta and white, which can be made through additive color mixing. As soon as 2 or 3 strands are supplied with voltage at the same time, the result is a mixed color. Furthermore, the traffic light colors of red, green, and yellow The multicolored illumination also allows multicolored colored status indications. Today these are used in customer-specific applications, e.g. in locked access areas to laboratory rooms. With this traffic light display (red, green, yellow) it is intuitively understood if one can enter the laboratory, if the room is currently occupied or Upon customer request, the supply voltage as well as the internal resistors can be removed. This creates the opportunity to present a broad color spectrum, which requires the addition of a microcontroller in the application to control the LED's. Enabling, for example, illumination in a specified company color and thus supports matching corporate identity design requirements. In addition, there is the possibility of varying the brightness depending on the design, which allows dimming. (RGY) version is also offered as a standard version. No additive color mixing is required to produce the color yellow. "Door Access" application example with a multicolored button in the RGB configuration

Multicolored Illuminated Piezo Switch Family for SCHURTER PSE - 2

Application Note if the room is being cleaned. Thus the SCHURTER PSE switch becomes an interactive input element that, at the same time, is a status indicator via the ring illumination. The PSE series is available in several versions. These range from a "marine grade" stainless steel housing to anodized aluminium housings in various colors. Additional Versions: As an alternative to the multicolored expansion, the PSE series is also available in the "EX" version with ATEX certification for applications in potentially explosive areas, which are used especially in environments with gases and...
