1. A safety switch actuation device for keeping a pushbutton switch activated and deactivated remotely, the actuation device comprising:
a plunger which can be brought by external probing from a standby position, in which the plunger does not switch the pushbutton switch, to an active position, in which the plunger keeps said pushbutton switch actuated;
a remotely controllable linear drive;
a return spring; and
a return actuator, wherein the actuation device is designed in such a way that the plunger can be coupled to the return actuator by the remotely controllable linear drive, which is driven by a Bowden cable, under tension of the return spring, wherein after deactivation of the linear drive, the plunger is pressed by the return spring into a position more remote from the pushbutton switch, thereby entraining the plunger into the standby position.
