  • Single-body actuating arms with a friction-reduction region that serves as a sliding surface
    Patent number: 10978264
    Abstract: The present invention relates to a start switch or contact point (10) for rotating electric machines with single-phase power supply, having a base (100) bearing actuating arms (200) carrying conductive blades (300). The actuating arms (200) are independent and one-piece, each one carrying at least one conductive blade (300) and being pressed against a stop (220) by a resilient element (400), also including a sliding surface (230) with a friction-reduction region (235). The present invention also relates to an electric machine provided with a corresponding start switch or contact point.
