A self-locking type automobile reading lamp switch disclosed by the present invention comprises a base, a pressing part, a shell and a pressing cover plate, the base is provided with a containing cavity, one side in the containing cavity is provided with a common terminal, a normally closed terminal and a normally open terminal, the outer side wall of the containing cavity is provided with a self-locking structure, one end of the pressing part is inserted into the containing cavity and abuts against the common terminal, and the other end of the pressing part abuts against the shell. One end of the shell is connected with a self-locking structure, the other end of the shell is connected with a self-locking hook, the self-locking hook is matched with the self-locking structure, one end of the shell is connected with the base, and the pressing cover plate is connected with the other end of the shell. According to the self-locking type automobile reading lamp switch, the self-locking mode of the self-locking hook and the self-locking structure is adopted, the pressing spring can be better locked when pressing the common terminal, the contact stability between the common terminal and the normally-open terminal is accordingly improved, meanwhile, the common terminal, the normally-closed terminal and the normally-open terminal are arranged on one side in the containing cavity, and therefore the contact stability between the common terminal and the normally-open terminal is improved. The pressing part is inserted into the containing cavity and abuts against the common terminal, so that side pressing is formed, and signal switching can be smoother through the side pressing mode.
