However, here & Tarch is the structure that is in the housing actual switching device adversely affected ..

The invention is based on the knowledge of these "assistants" and thus in the position of the task to eliminate them. According to the invention, the pressure pieces in switches of the type mentioned are not actuated directly, but by movement-transmitting means extending after the handle of the switch, preferably key levers (switch keys) lying next to one another, the free ends of which _; for their depression in the area of movement of the thumb of the: switch handle here / unchanged ■ '-.-.- lie firmly grasping the hand *'. .

This design enables reliable, fast, precise and convenient control of electrical drives by means of the manual switch. From!. The push pieces protruding from the switch housing can be attached to the switch that are favorable for the construction and dimensioning of the switchgear located in the switch housing with regard to its strength and operational safety as well as control of the switching capacity and its voltage.

The use of the locking lever results in the further advantage of the simple arrangement and design of an insertable and releasable locking device on the switch, which acts on the switching buttons each provided with a locking collar, with the locking device depressed when the locking device is engaged The switch button and thus the switch contact actuated by it remains in the switch-on position until the lock is released.
