The invention relates to a machine tool operating device comprising at least one operating unit (12a 12b 12c 12d), which has at least one operating element (14a 14b 14c 14d) that can be actuated by an operator, and comprising at least one electronic unit (16a 16b 16c 16d), which is provided for switching at least one energy supply of a drive unit (18a 18b 18c 18d) at least dependent on the actuation of the operating element (14a 14b 14c 14d). The electronic unit (16a 16b 16c 16d) has at least one locked switch function and at least one dead mans switch function which can be selected in an at least partly automatic manner at least depending on an actuation characteristic of the operating element (14a 14b 14c 14d) and/or at least depending on at least one detected sensor characteristic.
