Zusammenfassung:	A safety switch device (6) for the generation of a control signal (Theta) when the future angle of deflection of the housing of a rotary electrically powered hand tool exceeds a predetermined value, wherein a rotational rate sensor (7) directly measuring the rotational velocity (omega) is connected to a comparison element (8) in a signal-transferring fashion.
