Abstract
A variable resistance device wherein a slide member is disposed slidably within an elongated case, resistance and collector elements are disposed on an insulating substrate, and a contactor attached to the slide member rides over the resistance and collector elements. A common conductor and a pair of staggered change-over conductor strips are also disposed parallel to each other on the substrate, and a pair of change-over contactors engage with the common conductor and one of the change-over conductors, respectively. A pair of polar light source means disposed within the operating means of the slide member are connected in parallel with opposite polarity, and connected in common to the change-over contactors. One of the change-over contactors engages alternately with one or the other of the change-over conductors in accordance with the linear movement of the slide member, thereby the light source means changes its light alternately.
