A system for supplying electricity to a minimum of one electrical consumer on a piece of furniture in shop fitting, including: a minimum of one device for supplying electrical energy to the consumer or consumers, whereby, one supporting element is provided made from electrically insulating material, in particular made from a support film, which supports two electrical strip conductors that are each formed from an electrical conductive layer, each with a minimum of one electrical conductive contact surface per strip conductor on the source side, through which the strip conductor can be in contact with the source of voltage, with a very flat plug arranged on the support element that encompasses the ends of the strip conductors on the consumer sides whereby, the electrical connection to the consumer is through this plug; one or more supports, that presents either an element of the furniture or supports such an element and on which the consumer or consumers can be indirectly or directly attached; a minimum of one vertical profile, on which the support or the supports can be arranged and that features two vertically arranged conductor rails (51, 52), whereby, the profile is arranged in a housing; whereby, the device can be attached on the support, in particular by adhesion and the strip conductors on the support element can be supplied by electricity by hooking on, plugging in or hanging the support in the profile whereby, the support element features a self-adhesive layer of adhesive on one side and, on the other side, an electrically insulating protective layer and whereby, the support element is arranged to be flexible, in particular as support film. a minimum of one device for supplying electrical energy to the consumer or consumers, whereby, one supporting element is provided made from electrically insulating material, in particular made from a support film, which supports two electrical strip conductors that are each formed from an electrical conductive layer, each with a minimum of one electrical conductive contact surface per strip conductor on the source side, through which the strip conductor can be in contact with the source of voltage, with a very flat plug arranged on the support element that encompasses the ends of the strip conductors on the consumer sides whereby, the electrical connection to the consumer is through this plug; one or more supports, that presents either an element of the furniture or supports such an element and on which the consumer or consumers can be indirectly or directly attached; a minimum of one vertical profile, on which the support or the supports can be arranged and that features two vertically arranged conductor rails (51, 52), whereby, the profile is arranged in a housing; whereby, the device can be attached on the support, in particular by adhesion and the strip conductors on the support element can be supplied by electricity by hooking on, plugging in or hanging the support in the profile whereby, the support element features a self-adhesive layer of adhesive on one side and, on the other side, an electrically insulating protective layer and whereby, the support element is arranged to be flexible, in particular as support film.
