Power switch with bus bar connections, branch lines developed to reduce equipment costs without introducing limitations, esp. w.r.t. switch-on proof earthing - has two-position switches connected to main contact so earth potential of each earthing contact can be transferred via main contact

摘要

The power switch has three-position switches implemented as two-position switches (ZSS), each with a movable contact part (BKT) and each implemented with non switch-on proof earthing contacts. The two-position switches are connected to a main contact (HKO) so that the earth potential (EPO) of each earthing contact can be transferred via the main contact.
