摘要

The device (10) has three contact elements (18a-18c) comprising respective contact surfaces (20a-20c), where the device is integrated into a housing (16) of an interference suppressing device (14) of an electric motor. The contact elements are arranged at an edge of the housing, a middle area of the housing and another edge of the housing, respectively. A spring element is arranged between the interference suppressing device and a pole-packet unit of the electric motor and provided for loading the contact elements.
