Abstract
A switchable damper comprises a housing having a longitudinal axis, a plunger displaceable along the longitudinal axis, a piston arranged between the housing and the plunger, a friction lining arranged on the piston and a switching unit, which is switchable between a blocking arrangement, in which the piston is blocked with respect to a displacement along the longitudinal axis, and a free-moving arrangement, in which the piston is released with respect to a displacement along the longitudinal axis.
