Abstract
Abstract An electrical device has two electrical contact components (68,72) at least one of which is a pultruded composite member made of a plurality of small diameter conductive fibers (71) in a polymer matrix (75), the fibers being oriented in the matrix in a direction substantially parallel to the axial direction of the pultruded composite member and being continuous from one end of the member to the other to provide a plurality of potential electrical contacts at each end of the member.
