Abstract
The invention relates to a torsion spring assembly for a switching apparatus. The torsion spring assembly includes at least one torsion spring configured to be arranged around a pivot shaft for pivoting at least one movable arm between a closed position in which a current path is closed, and an open position in which the current path is open. The at least one torsion spring is configured to be connected to the pivot shaft at a first end, and to a base structure supporting the pivot shaft at a second end.

A torsion spring assembly for a switching apparatus, the torsion spring assembly comprising:
- at least one torsion spring configured to be arranged around a pivot shaft for pivoting at least one movable arm between a closed position in which a current path is closed, and an open position in which the current path is open,
- the at least one torsion spring being configured to be connected to the pivot shaft at a first end, and to a base structure supporting the pivot shaft at a second end.
A switching apparatus for an electrical circuit, the switching apparatus comprising:
- at least one movable arm connected to a pivot shaft for pivoting the at least one movable arm between a closed position in which a current path is closed, and an open position in which the current path is open;
- a base structure supporting the pivot shaft;
- and
- a torsion spring assembly comprising at least one torsion spring arranged around the pivot shaft and connected to the pivot shaft at a first end, and to the base structure at a second end.
A switching apparatus for an electrical circuit, the switching apparatus comprising:
- a base structure;
- a pivot shaft supported by the base structure;
- a movable arm pivotably connected to the pivot shaft, the movable arm being pivotable between a closed position to closer a current path, and an open position to open the current path;
- and
- a torsion spring arranged around the pivot shaft, the torsion spring comprising:
- a first end connected to the pivot shaft;
- and
- a second end connected to the base structure.
