Abstract

The design allows observation of the tripping pin to be made directly on switchgear housing, and the pin (24) is lengthwise movable in the housing (23) or the earthing switch (22), the right-hand end of the pin being linked to the connector (26). The latter is articulated to a crank (28) whose shaft (29) terminates with a square for engagement by a spanner. The left-hand end of the pin (24) operates contact fingers (31) and markings (32/33) appear alternatively through the looking window (34) to indicate the ON and OFF positions. The looking window (34) may have a reference marking (35, 36) which may have greater dimensions in the switch pin direction of motion than that on the pin proper.
