摘要

The switch has at least one switchboard arrangement (4) and two busbars (5,6). It switches the output between the busbars and is mounted between the output and the busbars. It has first and second contacts (19a,19b) to the busbars and a third (13) to the output. The output contact is connected to the first or second contact and to the system output (9), at least when the switch is in a state in which the first or second contact is connected to the first or second busbar.
