Abstract
Operating shaft 4 allows disconnecting switch-side and earthing switch-side moving contacts 7a and 7b to linearly reciprocate with the rotation of operating shaft 4. Operating shaft 4 has two-hole lever 5 allow an arc motion. Each one end of two curved links 6a and 6b is connected to two-hole lever 5 and the other end of two curved links 6a and 6b is respectively connected to the disconnecting switch-side moving contact or the earthing switch-side moving contact. When the two connecting points are axisymmetric with respect to the bisector, both the disconnecting switch and the earthing switch are in an open state; when two-hole lever 5 moves at a predetermined angle to the disconnecting switch-side, the disconnecting switch is in a closed state; and when two-hole lever 5 moves at a predetermined angle to the earthing switch-side, the earthing switch is in a closed state.
