EAO Series 56 Universal Switch

Intuitive and tactile. Reliable.

Combines visual and tactile feedback with a large actuation surface with clear symbols – for intuitive operation.


Olten, Switzerland, June 2020 – With the Series 56, EAO offers a pushbutton that has been used in millions of applications worldwide and offers an unmistakable, distinctive click when actuated – for an extraordinarily high level of user confidence. The Universal Switch is the latest member of the Series 56 family.

The Series 56 Universal Switch can always be located quickly, thanks to its LED illumination that is clearly visible at all times as well as its large actuation surface, range of colour options for the front bezel and laser engraved symbols. These features, combined with the unmistakable and distinctive click upon operation, ensure that the intuitive button offers an extraordinarily high level of user comfort.

Application examples

  • Transit buses and travel coaches
  • Technology used in buildings and infrastructure
  • Machinery

A wide range of standard, ISO 7000 or customer-specific symbols can be lasered in black onto the grey anodised symbol insets (not TSI PRM compliant). This versatility, in combination with the range of colour options for the front bezel, allows an application-specific design to be produced quickly and easily. Lenses without symbols are also available.


  • Intuitive operation thanks to visual and tactile feedback
  • Large actuation surface and various front bezel colours
  • Low mounting depth (27 mm incl. M8x1 standard connector)
  • Long, reliable service life (>5 million cycles of operation)
  • Standard, ISO 7000 or customer-specific laser Symbols

The pushbutton stands out at first glance thanks to its large actuation surface. The enabled state of the button is signalled by green lighting, which is easily visible even under adverse light conditions. The user receives multi-sensory feedback as soon as the button is pressed. This takes the form of the audible and tactile click that is typical for buttons in the Series 56 product family, as well as a clearly visible red LED in addition to the green illumination. Thanks to its standard M8 connector (M8x1, 6-pin) and low mounting depth (27 mm), the Series 56 Universal Switch offers easy plug & play installation.
