Abstract (en)
[origin: WO2008055701A1] The invention proposes a safety switch device for switching a power supply to a load on and off with at least one driveable switching element (1, 2, 21, 22), in particular a relay and a safety circuit (103, 104) for checking a switching state of the switching element. According to the invention, the switching element (1, 2, 21, 22) is in the form of a changeover switch in such a way that a first contact (1c, 2c) is electrically connected, by means of a switching operation, either to a second contact (1b, 2b) or a third contact (1a, 2a). In addition, the invention proposes a method for operating a safety switch device.
