<p>An electrical device comprises a substrate 2,4 supporting a film-type track 8, such as a heater track formed by depositing and curing a conductive polymer ink. A connector member 5 is provided which is bonded to the substrate 2,4, by means of a suitable adhesive 7, such as epoxy. The film-type track 8 is arranged to overlie at least an end portion 6 of the connector member 5 to provide a low electrical resistance contact therebetween. The arrangement permits the connector member to be mechanically bonded directly to the substrate 2,4, and not via the film-type track 8. The device may be used as a heater for mirrors, such as in car mirrors or mirrors for other applications, such as dentistry, where misting of the viewable mirror surface can be expected to occur.</p> |
