The door lamp switch according to the present invention has a socket portion 38 instead of the conventional switch cord for transmitting a signal to the outside, thereby reducing the size of the door lamp switch, it is possible to prevent the damage of the fixed ground portion 30 In addition, it is possible to prevent a short circuit due to infiltration of foreign matter.

Referring to the effects of the present invention configured as described above are as follows.

If the door is closed while the door switch is installed on the vehicle body, the push rod of the door lamp switch is lowered, which disconnects the contact between the (-) plate terminal and the (+) plate terminal grounded on the vehicle body, thereby connecting the in-vehicle instrument panel. The lamp installed on the top is "off". In other words, the door lamp switch is kept in the "off" state when the door is closed.

Then, when the door is opened, the pressing force acting on the push rod is released and the push rod lowered accordingly is returned to its original position by the elastic force of the elastic member installed between the upper and lower terminals of the negative plate terminal. The plate terminal and the positive plate terminal are connected to turn on the lamp installed on the dashboard of the vehicle.

The (-) plate terminal and the push rod, which is operated in this manner, are seated inside the cover part to protect against external shock and foreign substances, and the (-) plate terminal is firmly fixed to the vehicle body. In addition, the door lamp switch can prevent the disconnection of the connection line due to the switch operation because the movable portion is limited to the up and down operation of the push rod.

As described above, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. Therefore, the embodiments described above are to be understood as illustrative and not restrictive in all aspects. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

The present invention has a socket portion that can be connected to the external connector, the flow of the terminal is prevented during opening and closing of the door to prevent the disconnection of the connecting line, there is an effect that can be easily connected to the external connector.
