The invention relates to a switching device for contacts on a support, especially for board contacts whose contact link can be operated manually, via a transmission device, by means of a push-button body. It is provided that the transmission device consists of at least two flexible transmission arms which are supported on the one hand on the push-button body and on the other hand on the support, and which are connected to the contact link by flexible arms. Together with a portion of the transmission arms, these arms form a closed shape in the manner of a quadrilateral at whose one corner the push-button body is arranged and at whose diagonally opposite corner the contact link is arranged. In consequence, when the push-button body is operated, the contact link moves in the opposite direction thereto.
