The invention belongs to the field of electric switch parts and relates to a box type button switch converting device which comprises a base body. A movable contact is arranged above the base body. A connecting contact plate of the movable contact is connected with a locking spring through a partitioning plate. A sliding plate is arranged on the top face of the base body in an attaching mode. One end of the sliding plate is connected with a reset spring which enables the sliding plate to abut against the base body. A connecting button and a disconnecting button which are opposite are arranged on the bottom face of the base body respectively. A connecting clamping opening and a disconnecting clamping opening are formed in the positions, corresponding to the connecting button and the disconnecting button, of the sliding plate respectively. The connecting button is connected with a contact pressing plate. A receding-preventing limiting part is arranged at a free end of the contact pressing plate. The contact pressing plate penetrates through base body and the connecting clamping opening. The connecting button is pressed, the contact pressing plate is pushed and is in contact with the partitioning plate, so that the partitioning plate pushes the connecting contact plate, a circuit is connected, and the sliding plate blocks the limiting part to prevent the contact pressing plate from receding. The disconnecting button and a button rod are integrally connected, and the front end of the button rod is an oblique face matched with the disconnecting clamping opening.
