Non-touch traffic light button

The hygienic and weatherproof button

Crossing lights are an indispensable aid to pedestrians in road traffic. However, they must function quickly and reliably. Non-touch systems offer better hygiene but also have greater reliability requirements. 

Mayser's non-touch traffic light button is based on a capacitive system. For this purpose, Mayser has developed a switch element with a capacitive sensor surface. It generates an electrical field that recognises people. If a hand moves in the field, it changes the capacity. This signal then requests the green phase of the traffic light system. The great advantage of the system is that the capacitive object recognition also works in rain and snow – pedestrian protection is not dependant on the weather.


The newly developed technology can also be used for other non-touch applications where buttons are exposed to disruptive environmental influences.

Benefits of the non-touch traffic light button:

  • hygienic as no touch required;
  • the sensor can also be triggered when wearing gloves;
  • offers standardised electromagnetic compatibility (EN 50293:2013-02) with road traffic signal systems (and is therefore immune to electromagnetic interference from mobile phones and radios).
