(54) Control device


(57) The present invention relates to a control device (1) to be arranged to a three-position switching device including one axis wherein the switching motion is controlled from a common axis. The switching device is then controlled by turning the control shaft in the apparatus clockwise or counter-clockwise. The present invention provides a completely new solution that ensures a safe operation of the switching device and enables to carry out checking and servicing using simple means. The control device (1) of the invention comprises a housing (5) arranged at the switching device, and a control plate (7) arranged to move in the housing substantially along the surface of the apparatus receiving the switching device. Such a control plate comprises at least two crank openings (10) to be moved at the control shaft of the switching device. The use of the switching device can then be regulated by moving the crank openings or the necks (11, 12) on both sides thereof at the control shaft, thus preventing or allowing the manual controller controlling the switching device to be arranged to a tuning end (13) in the control shaft.
