- the switching bridge can be adjusted by means of the actuating means between the closed position and the open position.
- the actuating means may in this case comprise a lever, which is pivotably mounted between the "setting” and the “off” position on the additional module, a slide which can be displaced would also be conceivable in this case
- the lever may have a fork section with a first fork arm and a second fork arm, and when the lever is moved toward the "on" position, the first fork arm will bear against the fork Switching projection off.
- the cover has a barrier which is designed such that the cover can only be transferred into a position covering the operating section when the lever has been completely inserted into the "Ein
- the cover eg in the form of a flap, additionally recognizes whether the lever is in one of its end positions, and the barrier can also be configured in such a way that it can be locked in position closed cover, in which the operating portion is covered, the lever is not one r position can be transferred to the other position. This ensures that unintentional adjustment of the lever and thus inadvertent opening or closing of the electrical connection between the terminal contacts and the plug-in contacts is avoided.
