Abstract
A resiliently prestressed oscillatory system having two discrete operative positions is located by means of toggle levers in the limit positions of the oscillation. One of the toggle levers is in the extended state in the associated operative position and is deflected by a control device through the agency of a movable abutment until the self-locking of the toggle lever is overcome and a prestressed spring drives the system into its other end position. The toggle levers form an amplifier reducing, for instance, by a hundred-fold to a thousand-fold, the forces which the control device is required to provide. The system can therefore be controlled directly by means of an electronic control without the need for additional pneumatic of hydraulic auxiliary systems or high power electrical systems.
