- the transmission 15 may also have a different lever to the one described above exhibit. It can also be designed as a transmission of a different type be. For example, when using a rotating drive 2 could the transmission 15 from a shaft 1 5a and only a first rocker lever 14, be constructed without second rocker arm 20. Furthermore, but also more expensive Arrangements possible, for example, an angle translation include. The latter can serve to drive 2 to an existing Adapt the switching device when the drive 2 another stroke of the drive rod 24 than originally provided for the switching device.
- the shaft 15a By means of the shaft 15a, the distance between the first plane and the second, to be selected to the first level parallel plane, in which the longitudinal axis A of the drive rod 24 is located.

- the described numerous rotatable connections between the elements of the switching device can, for example, as bolt connections be educated.
- the lever lengths L and L ' can also be chosen different sizes, if the operational requirements require it. For example, if in a switching device, a drive 2 is to be fitted, the other hub the drive rod 24 or another force during the switching operation was originally intended for the switching device.
- the angle ⁇ does not have to be as large as shown in the figures be that the lever arm of the first rocker lever 14 parallel to a Straight line passing through positions P2 and P4.
