2. Description of the Related Art It has been practiced to tilt a door mirror up and down and left and right by an electric mechanism to adjust a field of view by remote control. Such operations require a so-called multi-directional switch. That is, a switch for tilting the mirror up and down by controlling a motor for tilting the mirror and a switch for tilting the mirror left and right are required, and a switch for switching between the adjustment of the right side mirror and the adjustment of the left side mirror of the vehicle body (commonly known as a selector switch) ) Is required, and furthermore, a storage switch for tilting and retracting the door mirror so as not to be in the way or extending to the functional posture is required. In order to perform these functions with a single switch device, for example, a four-way switch for operating up / down and left / right tilting of a mirror, and a selector switch for operating to switch between a right side mirror and a left side mirror of the vehicle body are provided. A multi-directional switch including a lock-type push switch for operating storage and extension of the door mirror is used. In order to facilitate the operation of the above-described multidirectional switch, an illumination mechanism for illuminating an operation mark provided on an operation member is also provided. FIG. 5 is a schematic exploded perspective view showing an outline of a multi-directional switch having an illumination mechanism, in which components (eg, packing, etc.) that are not important in structural functions are omitted. There is a function in which a left / right switch is added to the four-way switch.

The push plate 2 is a push plate for manual operation. The push plate 2 is provided with four transparent triangular arrow operation marks 2a indicating operation in four directions, and further faces a central opening 2b of the push plate 2. At the very least, a switch knob 3 for switching between left and right is provided. The push plate 2 is attached to the top of the case 6 so as to be tiltable,
The bottom opening of the case 6 is covered with a holder 16. The holder 16 supports a printed board 13 on which four push switches 7 and one slide switch 8 are arranged. The push switch 7 is operated by the push plate 2, and the slide switch 8 is operated by the switch knob 3. These switches are connected to an external circuit by a plurality of terminals 15 conducted to the printed circuit board 13. A lamp 14 is provided to illuminate the transparent operation mark of the push plate 2. This lamp 1
The light emitted from 4 is divided into four parts by the light guide lens 10 and guided upward in the figure to illuminate the transparent operation mark 2a from the inside. Japanese Patent Application No. 2-113100 is known as a prior art relating to a multidirectional switch with illumination.

[0004]

The above-mentioned lamp 14 is
Conventionally, it was generally soldered to the printed circuit board 13.
For this reason, even if the lamp 14 is worn out, it is very difficult to replace it. In practice, the switch assembly is discarded as a failed product without replacing the lamp. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has created a socket structure for a multidirectional switch with illumination that allows quick and easy replacement of a lamp.

[0005]

The basic principle of the socket structure according to the present invention created to achieve the above object is as follows.
The lamp can be mounted on a socket provided with terminals for conducting to an external circuit without soldering without electrically connecting the lamp to a printed circuit board. As a specific configuration based on the above principle, the socket structure according to the present invention includes a push plate having a transparent operation mark and a light source lamp, and a light guide between the light source lamp and the operation mark. In a multidirectional switch with illumination, in which a member is disposed and a terminal for supplying power to the high-source lamp is provided, a lead wire of the light source lamp is inserted into a hole provided in a socket. A tongue-shaped press-fitting piece formed in the terminal is press-fitted into the above-mentioned hole to contact and conduct with the lead wire, and the light source lamp is mounted.
When the socket is removed from the holder of the socket,
When the press-fitting piece of the terminal comes out of the hole, the light
It is characterized in that the source lamp can be easily attached and detached and replaced .

[0006]

According to the above arrangement, when the tongue-shaped portion of the terminal (hereinafter referred to as the terminal press-fitting piece) is pulled out of the hole of the socket, the lead wire of the lamp is released so that the old lamp can be easily removed. Can be removed. Then, by inserting a lead wire of a new lamp into the above-mentioned hole and press-fitting the press-fitting piece of the terminal, the replacement work can be performed quickly and easily.
