The invention discloses a door closing-opening indication device of an automobile door lock. The door closing-opening indication device comprises a claw support (1), a ratchet wheel (2) and a button microswitch (3), wherein a ratchet wheel pawl meshing transmission chamber (4) and an electric member chamber (5) which are isolated are arranged on the claw support (1); the ratchet wheel (2) is arranged inside the ratchet wheel pawl meshing transmission chamber (4); the button microswitch (3) is arranged inside the electric member chamber (5); and the ratchet wheel (2) is linked with the button microswitch (3) through a power transmission mechanism arranged inside the electric member chamber (5). As the ratchet wheel pawl meshing transmission chamber and the electric member chamber are independent and are not communicated mutually, the button microswitch can work in a relatively independent area, thereby being beneficial to meeting the working environment required highly by the electric member; the electric member can work smoothly in a comfortable environment, the dust or the greasy area where the ratchet wheel is meshed with the pawl is avoided; the working reliability of the electric member is improved sufficiently; and the assurance in safe running of the automobile is provided.
