Abstract:
1. A method of operating a mobile hand-operated device provided for outputting or enabling potentially dangerous control commands on a controllable technical device actively connected to the mobile hand-operated device or to another hand-operated device, in particular a robot or a machine tool, with a safety switch device comprising at least one evaluation circuit and at least one enable button connected to the at least one evaluation circuit for transmitting signals to the at least one evaluation circuit, the at least one enable button having an idle mode automatically assumed without operating force and having two consecutive operating modes set on a basis of at least one of differing strengths of operating force and different displacement distances, namely an enable operation mode and a panic operating mode, wherein in terms of control either a controllingly active mode or a controllingly inactive mode is electronically assigned to the at least one enable button, wherein in the controllingly active mode the at least one enable button can signal an enabling mode for running potentially dangerous control commands or assuming the enable operation mode allows an enabling mode to be made available, wherein in the controllingly inactive mode signalling or availability of the enabling mode is suppressed or not possible, wherein a check of the at least one enable button is run beforehand and the controllingly active mode is assigned to the at least one enable button when the at least one evaluation circuit has detected on a basis of signals from the at least one enable button that during the check that was run beforehand the panic operating mode has been assumed by the at least one enable button or that during the check that was run beforehand the panic operating mode and the idle mode have been assumed by the at least one enable button, and wherein a timer with a predefined sequence time is started when the at least one enable button assumes the panic operating mode or when the operating mode of the at least one enable button is switched from the panic operating mode to the enable operation mode or from the panic operating mode via the enable operation mode to the idle mode, and the signalling or availability of an enabling mode remains locked until it has elapsed.
