Abstract
A control device adapted to automatically stop an electric motor, said device comprising reduction gearing adapted to transfer the rotation of an electrically driven shaft to a toothed gear wheel 18. Two cam wheels 17 and 20 which are adapted to frictionally rotate with the toothed gear wheel 18. Two contact switches 21a and 21b that are activated by the respective cams on the cam wheels 17 and 20. Wherein the rotational orientation of the cam wheels 17 and 20 with respect to the toothed wheel 18 is infinitely adjustable. The friction between the toothed and cam wheels may be created by plastic and/or metal spring washer(s) 18a and 18b. The control device may be part of a motorized shutter.
