Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a switch device suitable for use in turning on and off a desk lamp, etc., and particularly relates to a switch device in which the switch is operated by a switch lever.

<Prior Art> A conventional switch device of this type, for example, a switch device for a desk lamp, is configured to switch a lamp attached to a shade supported by a support 1 of the desk lamp, as shown in FIGS. 5 and 6. A switch 2 for controlling energization is disposed in the lower body 4 of the main body 3, a switch lever 5 for pressing the switch 2 is provided with a shaft 6, and a groove 7 on one side of the switch lever 5 in which the switch 6 is provided is connected to the main body 3. A groove 9 is provided in the upper body 8 and the other groove 9 is provided in the lower body 10 of the main body 3 to form a fulcrum 11 of the switch lever 5. By pressing the surface of the switch lever 5, the fulcrum of the switch lever 5 can be adjusted. The switch 2 is rotated around the switch lever 5, and the switch 2 is pressed on the back side of the switch lever 5 to control the energization of the lamp and turn it on and off.

<Problems to be solved by the invention> In the switch device configured as described above, since the fulcrum 11 of the switch lever 5 is provided away from the top surface 12 of the main body 3, the switch lever 5 is If the gap 15 between the edge 13 on the opposite side of the fulcrum 11 and the vertical surface 14 of the upper body 8 of the main body 3 is made slightly larger, the edge of the switch lever 5 will be damaged when the switch lever 5 is pressed. 13 is main body 3
There is a drawback that the switch lever 5 cannot be pressed because it hits the vertical surface 14 of the upper body 8.
In order to eliminate this drawback, if the gap 15 is made slightly larger, the appearance will be poor and dust will be removed.
It had the disadvantage of allowing foreign matter to enter.

This invention eliminates the above drawbacks,
The purpose of this is to provide a switch device that has a structure that minimizes the gap to allow smooth press operation of the switch lever, has a good appearance, and can prevent the intrusion of dust, foreign matter, etc. .

<Means for Solving the Problems> The present invention is a switch device in which the switch 24 is operated by a switch lever 28, in which the fulcrum of the switch lever 28 is provided near the top surface of the main body 25.

<Function> By operating the switch lever 28, the switch lever 28 rotates around a fulcrum near the top surface of the switch lever 28, and the switch 24 is rotated by the switch lever 28.
It is used to operate.

<Embodiment> Hereinafter, a case where an embodiment of the switch device of the present invention is used as an on/off switch device for a desk lamp will be described with reference to FIGS. 1 to 4.

The switch device of the present invention includes a switch 24 that controls energization of a lamp 23 attached to a shade 22 supported by a support 21 of a desk lamp.
A top surface (top portion) 29 of a switch lever 28 having a triangular cross section is disposed on the upper body 26 having a triangular cross section, and presses and operates the push button lever 27 of the switch 24.
A rib 3 having a rounded surface 31 at the tip on the back surface 30 of the
2 and has rounded surfaces 33a and 33b spaced apart from the rib 32 by a predetermined distance.
a, 34b are provided on the side surfaces 35a, 35b, and has a radiused surface 36 on the front surface that abuts and pivots the radiused surface 31 of the rib 32, and a radiused surface 3 that abuts the radiused surface 33a of the one protrusion 34a on the back surface.
6a is provided on the top surface (top portion) 38a of the upper body 26, and the other protrusion 34
A pivot portion 37b having a rounded surface 36b that contacts the rounded surface 33b of b is provided on the top surface (top portion) 38b of the upper body 26, and a screw insertion hole 41 of the lower body 40 to which the upper body 26 is attached with a screw. A positioning pin 42 is provided which contacts the inner surface of the other side surface 35b of the switch lever 28 to position the other side surface 35b. Round surface 36 of the surface of branch 37a
The rounded surface 38a of one protrusion 34a of the switch lever 28 is brought into contact with the upper body 2.
6, and the other protrusion 3 of the switch lever 28
The switch lever 28 is fitted into the upper body 26 by contacting the radius surface 33b of the switch lever 28 with the radius surface 36b of the pivot portion 37b of the upper body 26, and the lower body 40 is fitted onto the inner surface of the other side surface 35b of the switch lever 28. The upper main body 26 is disposed on the lower main body 40 so that the positioning pin 42 of the upper main body 26 contacts the lower main body 40 for positioning (horizontal positioning).
6 and the lower main body 40 are fixed with screws.

In the above configuration, the switch 24 is configured to sequentially repeat the on state and off state each time the push button lever 27 is pressed by the switch lever 28.

In the switch device configured as described above, when the switch lever 28 is pressed, the switch lever 28 rotates about the rib 32 on the lower surface 29, and the push button lever 27 of the switch 24 is operated by the switch lever 28. The lamp 23 is pressed to turn it on and off, thereby controlling the energization of the lamp 23 to a predetermined state.

In the above case, when the switch lever 28 is pressed, the switch lever 28 moves substantially parallel to the slope 43 provided at a substantially right angle to the top surface of the upper body 26. In addition, since the fulcrum of the switch lever 28 is provided near the top surface, as shown in FIG.
The gap 45 with a can be made smaller.

<Effects of the invention> Since the switch device of the present invention has the above-mentioned configuration, it is possible to reduce the gap, improve the appearance, and prevent the intrusion of dust, foreign matter, etc. Furthermore, the switch lever is sandwiched between the upper body and can be easily removed from the upper body, so even if dust or foreign matter enters through the gap, the switch lever can be easily removed and the dust or foreign matter can be removed. This has the effect of being extremely easy to remove.
