Develop More Dynamic Control Panels with EAO Series 84 PCB Illuminated Pushbuttons

Milford, CT - EAO Corporation of Milford, CT USA, a premier global supplier of Human Machine Interface (HMI) Systems and Components, announces the Series 84 PCB, bringing multicolor "halo" illumination capabilities to design engineers working on HMI Systems and control panels.

The Series 84 PCB offers a range of 22.5 mm, PCB-mounted pushbuttons and indicators that can be quickly and easily programmed to change color, pulse, flash, and illuminate at the edge, creating a variety of dynamic effects. The Series 84 PCB allows design engineers to create exciting, engaging, animated, and intuitively easy-to-use control panels of any size. For example they can:

o Utilize 10 different SMD LEDs to produce customer-specific illumination combinations;

o Select eight outer ring LEDs to produce a "halo" and an additional bi-color LED for the center.

With the assistance of additionally supplied electronics, these switches can be used alongside touchscreens and displays to emphasize primary or additional controls to:

o Show initiation sequences with a dynamic LED countdown;

o Increase or decrease output - each time the button is pressed another LED lights up around the ring;

o Provide visual warning signals through the use of multiple colors or animated illumination sequences;

o Show various cycle stages of application by changing illumination.

The transparent actuator is mounted on the PCB using a flange with snap-on connector. There's a choice of flat or raised, plastic or aluminium lenses. The complete switch is quickly mounted in a 022.5 mm opening. Cost savings can be achieved in end user applications since several functions can be combined into one switch, thereby minimizing panel space and the need for multiple components.

Many of the world's leading manufacturers work with EAO as their partner for the integration of HMI Systems and Components with their mission-critical applications. Visit for more information on the Series 84 PCB. For information on EAO's HMI Systems expertise, visit
