An interlock system for actuating a switch to interrupt a flow of electrical current to a component of a domestic electrical appliance is described. Specifically, in one embodiment, the technique simplifies transformations in order to find one or more min-repros. Furthermore, a crossmember has such a connection arrangement. Where a plurality of the wireless menu responses are received from a plurality of electronic devices connected to the wireless LAN, the electronic device is selected by displaying a list of the plurality of electronic devices, and selecting one of the plurality of electronic devices based on user selection from the list. When the lock is engaged, the bag liner may be set in a self-standing manner for its edge, and an empty garbage bag easily placed over the liner. A similar device is able to bring, during successive weft insert cycles, a warp yarn alternately into the lower position and in any of the upper, center and lower positions, and has no pulley block elements.
