Abstract
A brush holder assembly for an electric motor and a method of making it. The assembly comprises a unitary structure formed of a molded plastic housing in which a stamped and formed metal circuit plate is encapsulated. Separate circuit strips are formed by punching circuit bridges out of the plate after it is encapsulated. The separate circuit strips are embedded in one face of a web spanning the housing. On the opposite face of the web, brush holder channels are molded. The separate circuit strips each have a terminal formed unitarily with them, the terminals being embedded in a socket extending radially, outward from the web through a skirt encircling the web.
