The Series 84 PCB pushbuttons offer multicolor “halo” illumination capabilities for HMI systems and control panels.

The range of 22.5-mm, PCB-mounted pushbuttons and indicators are quick and easy to program to change color, pulse, flash, and illuminate at the edge for a variety of dynamic effects. The devices use 10 different SMD LEDs to produce customer-specific illumination combinations. Users select eight outer ring LEDs to produce a “halo” and an additional bicolor LED for the center.

Along with additional electronics, the switches can be used with touchscreens and displays to emphasize primary or additional controls to show initiation sequences with a dynamic LED countdown; increase or decrease output – each time the button is pressed another LED lights up around the ring; provide visual warning signals through the use of multiple colors or animated illumination sequences;, and show various cycle stages of application by changing illumination.

The device mounts on a PCB using a flange with snap-on connector. Users can choose flat or raised, plastic or aluminium lenses.
