EAO Series 56: Universal illuminated pushbuttons


The manufacturer EAO, with Swiss origin, is the expert for "Human Machine Interfaces". These are products such as keyboards, push buttons, operating systems and units. The 56 series of buttons are used millions of times around the globe in mechanical engineering, in buses and in building control systems. Thanks to the large actuating surface, the all times illuminated LED ring, the user-specific laser symbols and a wide choice of colours for the front frame, the push-button ensures a high level of operating comfort. The characteristic click immediately provides unmistakable acoustic feedback. Actuation is additionally confirmed visually by the permanent LED illumination with red LEDs. The versatile areas of application are proven, among other things, by the long service life and the low installation depth of the product. The series is complemented by lever switches, warning sounders and warning flashing lights with the same and flexible design.
