EAO, the Expert Partner for Human Machine Interfaces, is now offering a switch with multicoloured ‘halo’ illumination for creating highly flexible displays.

The Series 84 PCB range of pushbuttons and indicators opens up new and previously unimagined possibilities for illuminated control panels. A wide spectrum of different colours can be generated from a single switch by utilizing the possibility to combine up to 10 different coloured LEDs in one unit: eight around the lens and one bi-colour in the middle.

When connected, the LEDs can be programmed to change colour, pulse, flash, illuminate the edge and create a variety of other disco-style effects. They not only add the WOW factor, they enable the status of more than one function to be displayed on a single switch. This makes it possible to create a feature-packed display or control panel in even the smallest areas.

The actuator, which is transparent, is mounted on the PCB by means of a newly developed flange with snap-on connector. There’s a choice of flat or raised, plastic or aluminum lenses. The complete switch fits into a Ø 22.5mm cut-out.

Series 84 PCB switches can be utilized for a variety of applications including ticket machines, instruments and medical devices, machine and process controls, and audio, video, general lighting and stagecraft.
