摘要： The invention relates to a pivot actuator (1), comprising: a housing (2); a piston (3) that is supported in the housing (2) and displaceable along a longitudinal axis (7) of the housing; a drive shalt (4) that protrudes from the housing (2) wherein the piston (3) engages the drive shaft (4) by form locking so that the drive shaft (4) is pivoted about a drive axis (8) by a pivot angle between two end positions through a displacement of the piston; and a switching cam (11) that is fixed torque proof at the drive shaft and configured to contact a stop element (5) at the housing (2) with a respective contact surface (ill) of the switch cam in the two end positions, characterized in that the switching cam (11) includes two discs (15) that are arranged adjacent to one another along the drive axis (8), wherein one respective contact surface (18) of the two contact surfaces (18) is arranged at each of the two discs (15) respectively.
