Safety switch actuation device

Abstract

An actuation device for keeping the pushbutton switch activated and deactivated remotely. The actuation device includes a plunger which can be brought by external probing from a standby position, in which it does not switch the pushbutton switch, to an active position, in which it keeps the pushbutton switch actuated. The actuation device has a remotely controllable linear drive, a return spring and a return actuator and is designed in such a way that the plunger can be coupled to the return actuator by the remotely controllable linear drive, which is preferably 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 its standby position.
