Abstract (en)
A high voltage switch (10) comprises a movable electric contact (12) movable with respect to a further electric contact (14) between a closed position, in which the electric contacts (12, 14) are connected and an opened position, in which the electric contacts (12, 14) are disconnected, and a position sensor (24) for determining a position (64) of the movable electric contact (12). The position sensor (24) comprises a sensor bar (30) with a light emitting side (46) and a light receiving side (48); a code strip (28) comprising a transparent pattern (60), wherein the code strip (28) is arranged between the light emitting side (46) and the light receiving side (48); an electric sensor part (27) comprising a light source (40) and at least one light receiver (42) for converting a light signal into an electric signal; and fibre optics lines (32, 34) for connecting the light source (40) with the light emitting side (46) and for connecting the light receiving side (48) with the at least one light receiver (42). The code strip (28) and the sensor bar (30) are attached to the high voltage switch (10) such that a movement of the movable electrical contact (12) is conveyed in a relative movement of the code strip (28) and the sensor bar (30).
