ABSTRACT:
Switch contacts are placed on a thermoplastic stator body in their desired positions and a thermoplastic holding member is pressed onto the switch contacts. The holding member is then ultrasonically or otherwise thermally welded to the stator body in such a manner that the melted portions of the holding member between the switch contacts are deformed into contact with and welded to the stator body. A groove is formed in the stator body perpendicular to the switch contacts into which excess material of the holding member flows during the welding process.
