New Series 57 Tri-Colour version.

Multi-status indication thanks to tri-colour LED illumination.

Olten, Switzerland, May 2021 – EAO, the expert partner for innovative, intuitive and reliable Human Machine Interfaces (HMIs) and the pioneer of illuminated pushbuttons, sets a new standard with door opening pushbuttons in public transport with its innovative and market leading Series 57.

With the Tri-Colour Version of the Series 57 door opening pushbutton, a third colour can now be displayed in the outer feedback ring by the addition of two new LEDs. These new indicators, along with the standard two feedback rings of individual illumination, make it possible to indicate additional warnings such as ‘door fault’ or a ‘door closing and opening’ by means of independent, flashing LEDs.

Advantages of the Tri-Colour Version
  • Tri-colour, individual LED illumination of the feedback rings
  • Extra-large Ø 74 mm operating area
  • Raised symbols conform to TSI PRM & ADA
  • Consistent look & feel of Series 57 product family
User-friendly features include an extra-large Ø 74 mm operating area and two independently illuminated feedback rings that fully comply with EN 14752. The additional user benefits of the raised symbols (conform to TSI PRM & ADA) make this unique “all-in-one” door opening pushbutton the best in class. Furthermore, the optical, tactile and acoustic feedback is unbeatable.
