Sliprings are used in electrical - mechanical systems where a unin-
terruptible current or signal transmission from a static to an rotating object has to
be to proceed. The encapsulated sliprings are integrated into a metal housing, this
avoids the infl uence of interferences. Special wipers are sliding on a track, wiper
and track are formed to fi t perfectly into each other. This construction enlarges the
contact surface , reduces current noises and improves the life time performances.
