Abstract
A retractable hand lever actuator which can be locked in a trough for driving a latch for a switch cabinet or the like is described. The hand lever is articulated at a drive shaft supported in the trough. According to the invention, the hand lever actuator comprises a handle such as a T-handle or L-handle having two connection levers which are arranged relative to one another in a parallelogram configuration and which are articulated by one end at the drive shaft and by the other end in a similar manner at the handle in such a way that, on the one hand, they hold the handle in its direction parallel to the extension of the trough when the handle is folded out of the trough and, on the other hand, are able to transmit a rotational movement of the handle to the drive shaft in the folded out position.
