Abstract (en)

[origin: WO0137302A1] The invention relates to a safety switch device (10), for switching on and safely switching off an electrical user, in particular, an electrically-driven machine (34), comprising a first (14) and a second (16) electromechanical switch element, whose working contacts (18, 20) are arranged in series with each other, between a first input terminal (30) and an output terminal (32) of the switch device. The switch device (10), furthermore, comprises a second input terminal (38) for a switching signal (Us), which acts upon the switch position of the working contacts (18, 20) of both switch elements (14, 16). The invention is characterised in that the first switch element (14) has a lower nominal switching capacity than the second switching unit (16).
