The utility model provides a column switch device, include: column switch is including first moving contact and first static contact, isolator is including second moving contact and second static contact, first moving contact and second moving contact are connected to the link gear for first moving contact and second moving contact break off simultaneously or are closed. Use the technical scheme of the utility model, since be provided with the link gear between first moving contact and the second moving contact, can be in order to make first moving contact and second moving contact simultaneous movement, disconnection simultaneously or closed simultaneously to switching when having realized column switch and isolator has been avoided because the inconsistent circumstances of column switch and isolator's break -make takes place, has improved column switch device's operational safety.
