The first member is provided with a magnet and the second member is provided with a screw to be attracted by the magnet for temporary combination of the first member and the second member. The first member is provided with a first sub-circuit and the second member is provided with a second sub-circuit. The first sub-circuit is electrically connected to the second sub-circuit to generate a circuitry when the first member and the second member are combined together. The circuitry will turn to a broken circuitry when the first member and the second member separate.
