Abstract: A switching apparatus alternately connects a mobile radio module and an E-Call controller to an antenna/ The switching apparatus includes a first signal input, a second signal input, an antenna connection and a changeover device that changes between a first switching state and a second switching state, based on at least one switching signal. In the first switching state, only the first signal input is electrically connected to the antenna connection, and in the second switching state, only the second signal input is electrically connected to the antenna connection. To prevent a connected transmission devices from diagnosing decoupling from the antenna connection as a fault, in at least the second switching state the changeover device electrically connects the signal input that is decoupled from the antenna connection to a terminating device which emulates an antenna at the signal input that is connected to the terminating device.

Abstract: An accessory unit of a vacuum cleaner, alone, with a vacuum cleaner conduit, and with a vacuum cleaner. The accessory unit has a housing, a first tool end, and a second tool end for releasable connection to a vacuum cleaner conduit. The first tool end has a first nozzle for vacuum cleaning, and the second tool end has two pivotable arms for forming second and third nozzles. Each arm has distal and proximal ends. The distal ends are arranged to be brought together for forming the second nozzle, and to be spread apart for forming the third nozzle. Furthermore, the arms are folded together to bring the distal arm ends in vicinity of each other for releasable connection of the second tool end to the vacuum cleaner conduit by at least partial insertion into said vacuum cleaner conduit.
