[origin: EP1628020A2] The hydraulic switch has a fluid return line (118a, 118c, 148) which is separated from the fluid input line (118a, 118b, 118c), at least in sectors. The switchable valve (132, 134), which is switchable between positions allowing or preventing the fluid return flow, is fitted in the sector of fluid return line which is separated from the fluid input line.
