The railway professional.
The FBS, a special version of the VNS0, is a switch developed for travel and braking operations used in trams and numerous other railway vehicles. It has been field-tested in practice over many years and has an impressively long service life and high reliability. In addition to its modular ergonomic design, it is resistant to ozone and UV radiation, so it can withstand harsh evironmental conditions. The deadman function provided with various handle shapes can be achieved either by mechanical-electrical means or with capacitive sensors and evaluating electronics. Possible switch versions vary from simple step switches to potentiometer switches to switches with encoders.
