HST Series hand rail button pushbuttons are particularly durable thanks to their robust housing and compact construction type. Underlying inscriptions and pictographs are protected by scratch-resistant, transparent polyamide. This ensures that the push buttons always look good and prevents the pictographs from fading, thus guaranteeing the contrast values. The minimum contrast value according to EN 16584-1:2017 and EU Regulation No. 1300/2014 (TSI PRM:2019) is required not only when newly installed, but also for the long term.
Optional haptic feedback using vibration (HSTIV model), which is particularly used in Scandinavia, is a hand rail button innovation.Passengers receive immediate haptic feedback when they press the button. This additional tactile feedback is intended to provide visually impaired passengers more comfort and safety when using buses and trains.
The variants with braille and raised pictographs also meet the special requirements of the TSI PRM and EU directives to ensure optimum support for persons with reduced mobility.
