BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch-equipped lamp suitable for use in vehicle interior lighting.

[0002]

2. Description of the Related Art As a lamp fixture with a switch of this type, there is a conventional one described in, for example, Japanese Utility Model Laid-Open No. 2-34016. This conventional technique is a lamp in which a lamp can be turned on and off by a switch associated with a lamp socket attached to an insulating plate, an insulating substrate having a socket insertion portion having opposing projections, a pair of holding pieces and a connection. Lamp sockets, each of which has a piece and is provided in the socket insertion portion through the protrusion with a mounting hole formed in the holding piece, and a switch integrally formed on the other side of the insulating substrate in the vicinity of each lamp socket. A tubular body for knob insertion, a movable contact piece that slides on a fixed contact piece extending from the connection piece exposed on the inner wall surface of the cylinder body, and another fixed contact piece having a connection terminal, together with a spring, in the switch knob. A switch-equipped lamp including a self-projecting push switch mounted in a cylinder and a lamp mounted between the pair of lamp sockets. A.

The above-mentioned prior art is a constant lighting type lighting device using a self-returning push switch, and although it can be used for lighting a passenger compartment such as a trunk room, it cannot be used as an illuminating lamp in a passenger compartment. The connection to the power supply line is inconvenient because it is soldered to the terminal piece, and there is a problem that the terminal piece itself is exposed and is easy to move, unstable and dangerous.

In order to eliminate the above-mentioned problems, the present invention can be turned off at a desired time by operating a slide switch, can be one-touch connected to a power supply line by a plug-in jack, and has a plug cover integrally formed with a switch cover. The purpose is to securely support the plug base while protecting it with.

SUMMARY OF THE INVENTION The above-mentioned object of the present invention is to provide a switch-equipped lamp for blinking a lamp inserted in the socket with a switch connected to a socket opposite the insulating plate. The sliding piece with the knob on the lower surface and the movable contact piece on the upper surface is stored in the elongated recess that is connected to the concave surface formed on the side edge of the A plurality of fixed contact pieces contacting the contact piece are respectively arranged in parallel by engaging with the concave surface portions of the side edges,
Further, of these fixed contact pieces, the rising portions of the fixed contact pieces on both sides passing through the concave surface portions are respectively bent outward to form plug pieces, and the rising folds of the central fixed contact pieces passing through the concave surface portions are further formed. The bent extending portion is connected to one of the sockets, the bent extending portion of the plug piece arranged in the concave portion between the plug pieces is connected to the other of the sockets, and the bent extending portion is engaged with the upper edge of the elongated recess. Position the fixed contact piece with the attached switch lid,
In addition, the plug cover integrally formed on the surface of the switch lid is inserted into the plug piece through the hole to protect these plugs.

[0006]

[Operation] The fixed contact piece and the plug piece are respectively positioned at the concave base portion on the side edge of the insulating plate at the rising base portion,
Moreover, the fixed contact piece can be located in the inner surface groove of the switch lid or the upper edge groove of the recess, and the plug piece can be located in its base portion in the hole of the plug cover. Therefore, the fixed contact piece does not indiscriminately move due to a disturbance such as sliding contact friction with the movable contact piece, and the plug piece does not stick to the insertion and removal of the separately provided multi-jack.

Then, the power source positive pole is connected to the plug piece and the plug piece is directly connected to the negative pole, and the plug piece is connected to the power source negative pole via the door switch, and the sliding piece is moved and fixed by the movable contact piece. By individually short-circuiting the contact pieces, the lamps can be turned on manually or when the door is opened.

Further, if the movable contact piece is further moved to a position where the short circuit between the fixed contact pieces is released, the lamp can be constantly turned off in the daytime.

Further, if the movable contact piece 5b is further moved to a position where the short circuit between the fixed contact pieces 6a to 6c is released as shown in FIG. 10, the lamp L can be constantly turned off in the daytime.

[0025]

Since the present invention is constructed as described above, it has the following effects. Fixed contact piece 6a ~ 6c
And the plug pieces 7a to 7c are respectively positioned by the concave bases 3a to 3d of the side edge 3 of the insulating plate at the rising bases of these pieces, and the fixed contact pieces 6a to 6c are the inner surface grooves or recesses of the switch lid 8. Localize with the upper edge groove of 4 and plug piece 7a ~
7c has the first effect that it can be used safely and reliably and easily because its base can be localized in the holes 9a to 9c of the plug cover 9.

In particular, the fixed contact pieces 6a to 6c do not move unintentionally due to a disturbance such as sliding contact friction with the movable contact piece 5b, and the plug pieces 7a to 7c are also attached and removed when the separately installed multijack or the like is inserted. There is also a second effect that it can be securely connected to the power supply line even with one-touch operation.

Furthermore, since the plug cover 9 is integrally formed on the surface of the switch lid 8, it is advantageous in terms of cost, and the plug cover 9 itself does not move unintentionally and is stable.
There is also a third effect that 7a to 7c can be protected.
