ABSTRACT:
An electrical switching device has a state indicator which is covered or uncovered in accordance with the state of the switching device. In order to reduce the amount of moved masses, the state indicator remains in a resting position during a switching process of the electrical switching device. The state indicator can be covered at least in part by the movable switching contact pieces of the electrical switching device, for example.
