Title of Invention

"THREE-POSITION GROUND SWITCH"

Abstract The high or medium voltage electrical switch, particularly a GIS type isolating switch with three switching positions and an earthing position comprises a switching element (7) in a closed and sealed enclosure (1) that can be filled with a dielectrically insulating gas, containing a mobile switching element free to move along an axial direction (D) to electrically connect two conducting bars (4, 5) at intervals from each other, and also including a fixed earthing contact (6) that will be electrically connected to one of the two conducting bars through the switching element when the switch is in the earthing position. The fixed earthing contact (6) is offset from the path of the switching element (7) along the said axial direction and the switching element forms a Y with a contact pin (8) such that the contact pin and the fixed earthing contact engage in each other through displacement of the switching element along the said axial direction.
Full Text WE CLAIM:
1. Electrical switch, comprising a first conducting bar (4) with axis (D), a second conducting bar (5) with an axis perpendicular to the axis (D) of the first conducting bar (4) that has an end at a spacing from the first conducting bar (5), a fixed earthing contact that will be electrically connected to the first conducting bar, a switching element (7) free to move along the axial direction (D) between an earthing position in which the first and second conducting bars are separated from each other and a switching position in which the first and second conducting bars are connected to each other, characterised in that the switching element (7) comprises a contact pin (8) parallel to the axis (D) and located at a distance from this axis, such that the fixed earthing contact (6) and the contact pin (8) engage in each other through displacement of the switching element along the axial direction (D), the earthing and switching positions located on each side of the an open position.
2. Electrical switch according to claim 1, wherein a first fixed breaking contact (11) of one of the two conducting bars and a second fixed breaking contact of the second conducting bar (5) are positioned on the same axial direction (D) of a sliding axial part (9) of the electrically conducting switching element (7).

3. Electrical switch according to claim 1 or 2, in which the sliding part of the switching element (7) is a rod (9) that slides along the said axial direction inside one (4) of the two conducting bars, the contact pin with the rod forming a Y.
4. Electrical switch according to claim 3, in which the rod (9) of the switching element engages in a hollow fixed breaking contact (12) fixed onto the other conducting bar (5).
5. Electrical switch according to claim 1 or 2, in which the sliding part of the switching element (7) is a sleeve (9') that slides on one (4) of the two conducting bars along the said axial direction, the contact pin with the sleeve forming a Y.
6. Electrical switch according to claim 4, in which the sleeve (9') of the switching element engages on a fixed breaking contact (12') in the form of a mushroom fixed on the other conducting bar (5).

7. Electrical switch according to one of claims 1 to 6, in which the fixed earthing contact (6) comprises a conducting part (6'A) with a hollow contact provided with elastic contact pins and into which the contact pin of the mobile Switching element engages.
8. Electrical switch according to one of claims 1 to 6, in which the fixed earthing contact (6) is a rod and the contact pin of the mobile switching element lhas a tulip-shaped hollow end into which the fixed earthing contact engages.
9. Electrical switch according to one of claims 1 to 8, in which the fixed earthing contact (6') is embedded partly in a support plate (2) made of an insulating material closing the enclosure.
