Abstract

A sliding electrical contact brush consists of a multi-layer packet. The layers are of electrically conducting sheet bonded together with an adhesive based upon a polymer binding agent, pref. a conducting binding agent, esp. contg. metal particles in a colloidal state. Pref. binding agent is a thermosetting resin, esp. polyvinyl furfural.
