According to an embodiment of the invention, a motor starter includes a connection module, which includes a second and third interface, wherein the second interface is electrically conductively connected to the third interface. The security evaluation unit can be mechanically coupled to the connection module so that an electrically conductive connection is produced between the first and second interfaces. The secure switch unit can be mechanically coupled to the connection module so that an electrically conductive connection between the third and fourth interfaces is produced, so that, in the coupled state of the security evaluation unit and the secure switch unit to the connection module; there is an electrically conductive connection between the first and fourth interfaces via the connection module, so that the control command can be transmitted from the security evaluation unit via the connection module to the secure switch unit.

At least one embodiment of the invention relates to a protective circuit for protection of an appliance, in particular of an electric motor, against thermal overloading. In at least one embodiment, the protective circuit includes a first and a second terminal for connecting a temperature detection element; a detection unit for detecting whether a resistance value of the temperature detector element which is connected between the first and the second terminals, is in a first or a second resistance range; a short-circuit detector for identifying whether there is a short circuit between the first and the second terminals; signaling outputs for emitting signal messages to an evaluation unit when the detected resistance value is in the second resistance range and/or when a short circuit has been identified by the short-circuit detector; and a third terminal, which is connected to the second terminal via a predetermined resistance.

A mirror support assembly for a motor vehicle comprising an upper support arm, an upper mounting element for mounting the upper support arms to the vehicle, a lower support arm, and a lower mounting element for mounting the lower support arm to the vehicle. A mirror head brace for uniting the upper and lower support arms includes a cast structural member made by pressure casting. The mirror head brace includes at least one longitudinal groove which determines a defined angular setting between the mirror head brace and the upper and lower support arms. The plurality of scorings functionally determine different angular settings relative to the mirror support arms of a mirror head 12 which is carried by mirror head brace.
