About the CK Series

The development of the Combikey push button is based on an unusual request that TSL-ESCHA received from North America: a US prison needed a bulletproof push button. England’s public transport system also needed robust push buttons, with demand for them increasing due to increased vandalism. We thus developed a robust and flat TSL push button with a completely metallic outer surface – the CK.

The CK push button family is characterized by a wide range of possible combinations: various circuit diagrams, touch surfaces, front panels, LED colors, pictographs and tactile symbols. A variety of light and sound signals are available to suit your specific requirements. An hourglass effect display is another option in order to indicate waiting times in front of doors. Combikey door opening push buttons have already proven their quality in buses, trams, subways, as well as in regional and high-speed trains for many years.

The CK push button’s modular design

The front panels are made of stainless steel. Another plus point: the CK push button is flat in design and installation, making the Combikey the ideal solution for thin walls and narrow passages. The flat design also facilitates cleaning.

In order to protect the pictogram, TSL-ESCHA invented a transparent button surface that shields against wear and tear as well as vandalism. To ensure that the touch surface remains durable and resistant, a special coating option provides protection against graffiti removers and aggressive cleaning agents.

CK’s modular design makes it possible to combine pictograms and tactile touch surfaces. The tactile symbols are raised and their shape and size meet legal requirements and those set by the EN 14752 standard (side entry systems for rail vehicles) and TSI-PRM (Technical Specification for Interoperability − Accessibility for persons with reduced mobility).

With the integration of touchless technology, TSL-ESCHA is expending its successful Combikey (CK) push button series and offers a product variation which additionally enables touchless activation of the push button.
