An auxiliary switch device for a switchgear according to the present invention includes a switching link which is eccentrically combined to the rotation center of a driving link and rotates clockwise or counterclockwise according to the rotation of a driving motor, and a sub switch which is combined with the switching link to rotate clockwise or counterclockwise and generates an input or open signal. Thereby, a force transmitted to an auxiliary switch can be kept according to the direct transmission of the torque of the driving motor to the auxiliary switch through a phased link. Also, the operation reliability of the auxiliary switch can be improved and safe accidents on a track can be prevented in advance. |
