Metal line switches with multi-colour illumination

Schurter's PSE piezo metal switch and MCS 30 mechanical metal switch series now with new illumination possibilities powered by variable input voltages.

Based on RGB colour technology, it’s now possible to indicate up to seven illumination colour options with just one switch. The variable power supply offers a homogeneous and brilliant illumination within a voltage range of 5 to 28 Vdc.

The new multi-colour illumination is facilitated using convenient colour-coded wires in each of the illumination colours. Each colour is given a specific voltage between 5 to 28 Vdc and a constant brightness intensity is maintained regardless of applied voltage.

The standard version is offered in red, green, and blue. Additional colour options include yellow, cyan, magenta and white, which can be made through additive color mixing. As soon as the 2 or 3 wires are supplied with the applied voltage at the same time, the result is a mixed colour. The traffic light colours of red, green and yellow for status indication are also available as a standard version. No additive colour mixing is required to produce the colour yellow. 
 
The new RGB multi-colour illumination option greatly expands the application range of the PSE and MCS 30 button style switches. The PSE is available in 22, 24, 27 and 30mm diameters; the MCS 30 is available with a 30mm diameter.

The PSE is IP69K rated. It has no moving actuator and is protected against moisture ingress or accumulation of dirt in the vicinity of the switch surface. This technology is suitable for hygiene-related applications such as medical equipment, food processing equipment and outdoor applications subject to vandalism such as ticketing machines. 
 
The MCS 30 is an alternative to the highly robust, solid state PSE. It is also designed for demanding applications, although it uses a tactile switch that provides a positive feedback of activation. It has a lifetime rating of one million actuations, as opposed to the PSE's 20 million operations. The switch contacts are sealed from the front and rated IP65.
