A storage receptacle 13 arranged in an inner door trim panel 10 of a motor vehicle has an access opening 9. The storage receptacle 13 also has an illumination device 15, a switching arrangement 16 for sensing a hand entering within the receptacle. The switching arrangement 16 comprises comprising a sensing electrode 17 arranged on the receptacle 13, a capacitance measuring means 19 comprising an frequency generator 18 connected to the sensing electrode 17, a switching device 20 arranged to operate in response to a change in the capacitance sensed by the measuring means and a shielding electrode 23 arranged on the receptacle 13. The shielding electrode 23 is connected to have the same electrostatic potential as the sensing electrode. The arrangement 16 is such that the shielding electrode 23 prevents operation of the switching device 20 by an object in or adjacent the receptacle 13 except by a hand moving towards or away from the access opening 9. |
