The PKM indicator light’s design is similar to the tried-and-tested PK push button from TSL-ESCHA. Depending on the installation situation, the illuminated pictographs inform passengers about various statuses. This indicator and display device is often installed in the door area, where it indicates a door defect, for example. Text and pictographs are printed to allow for the disappearing effect. This means that they can only be read when they are backlit.

Thanks to many years of usage in the transport industry and their robust design, TSL’s indicator lights have established themselves in the market. The PKM fits perfectly into the door structure and has the same installation dimensions as a door opening push button. As with the push button, the PKM indicator light can also be installed on both sides of the glass door. The optional LED color variants round off the functions of the PKM.
