A switch using one or more flexible circuit members provides for rolling contact between circuit members. One circuit member is attached to and wraps round a roller, and the other circuit member, which may be flexible or rigid is supported so that as the roller rotates it rolls, the circuit member attached to the roller changing its contact position with the other circuit member. Conductive patterns on the circuit members are moved into contact and out of contact with each other and can provide varying forms of switching arrangements, for example, normally made to break, normally broken to make, and transfer. Electronic devices can be mounted on either or both circuit members.
