Abstract
In a switch actuator for movable frogs (1), comprising at least one cylinder piston unit (5) having a defined preset piston stroke, the cylinder piston unit (5) is connected with bearings (6) capable of being displaced in the axial direction of the piston stroke, which bearings are connected with a stationary substructure for the adjustment of a defined center position of the piston stroke and the driver for the movable frog (1). The driver for the movable frog (1) is coupled with the cylinder piston unit (5) with first stops (9) displaceable in the axial direction being interposed.
