Abstract: A contact brush made in the form of a lamination composed of electroconductive foil laminae joined together with an adhesive on the base of a polymeric binder. As a binder use may be made of thermoreactive polymeric resins filled with colloidal metal particles, antifrictional and polish-forming admixtures which impart electric conductivity, high wear resistance and electric contact stability to the adhesive under conditions of elevated humidity and in a vacuum.The contact brush is intended for use in electrical machines, in particular, electric fractional horsepower motors, measuring potentiometers, start-control devices and the like where it is necessary to provide for a reliable and highly stable sliding electric contact.
