Abstract

The switch appts. has three rotary breaker switches (1) and six earthing switches (2), each of which has a stationary contact (10) and a cooperating switch contact (12) attached to a pivot arm (11), rotated via a coupled drive shaft (14). The pivot arm mounting (13) and the drive shaft (14) are applicable to four different types of pivot cam (11). The pivot arm mounting (13) is formed from a flat material with the pivot arm (11) selectively attached to one or other side.
