DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present embodiment will be described below in detail with reference to the drawings. FIG. 1 is a front sectional view showing an opening / closing contact portion of a first embodiment of an illuminating tilt switch according to the present invention, and FIG. 2 is a schematic center sectional view thereof. FIG. 3 is a side sectional view, and FIG. 4 is an exploded perspective view.

In these figures, a fixed contact 9 is provided on one side of a housing 16 which is a housing of the switch body.
The movable contact piece 4 formed by bending an elastic member such as phosphor bronze into a U-shape is attached to the movable contact piece 7 at one end of the movable contact piece 7 by caulking and fixing the contact terminal 8 to which is attached and the common terminal 10 forming the receiving portion 11. The concave portion 6 formed by bending a part of the recessed portion is placed in contact with the receiving portion 11 to form an opening / closing contact portion. One free end of the movable contact piece 4 bent in a U-shape is opened upward, and is pressed by a projecting piece 2 described later to urge the contact force.

An intermediate wall 19 is formed in the center of the housing 16 and a terminal hole 20 into which the terminal of the light emitting body 12 is inserted is formed to penetrate to the outside. The light emitting body 12 is disposed substantially in the center of the switch body. Have been. In this embodiment, an LED is used as the light emitter 12. And
After the LED terminal is once led out of the switch body, it is fixed to the terminal 13 fixed to the other side surface of the housing 16 with the protruding portion 14 so as to face the opening / closing contact portion. .

On the other hand, a tilting shaft 3 is formed opposite to the button 1, and the tilting shaft 3 is locked in a lateral hole 18 formed in the housing 16 so as to be tiltable left and right. A protruding piece 2 is provided below the tilting shaft 3 of the button 1 and presses the vicinity of the free end of the movable contact piece 4 bent in a U-shape as described above to urge the contact force.

In the illuminating tilt switch thus constructed, the opening / closing contact portion and the projecting piece 2 of the button 1 for driving the opening / closing contact portion are arranged along the side wall of the switch body. Since there is no projection inside the button that creates a shadow due to the light from the illuminant, the button 1 is characterized in that the illuminated state on the surface is uniform and a bright illuminated surface can be formed.

Reference numeral 15 denotes a filter formed of a colored translucent member or the like. Since the filter 15 made of a translucent member is provided inside the button 1, the luminous body 12 is not visible from the outside even if the button 1 is made of a transparent member, so it is necessary to knurl the button 1. And a clean appearance can be formed. FIG. 9 is a top view of the illuminating tilt switch of the present invention in which characters are displayed on the upper surface of the filter 15. As compared with the conventional illuminating tilt switch shown in FIGS. 7 and 8, an excellent design in which knurls and shadows do not disturb the display can be obtained.

FIG. 5 is an exploded perspective view showing another embodiment of the illuminating tilt switch of the present invention. In the present embodiment, a neon sphere 32 is disposed as a light emitter between open / close contact portions forming two poles as a power switch.

When the neon sphere 32 is used as a luminous body, a transparent member is used for the button 21 due to the luminance,
The inner surface of the button 21 is knurled. In this embodiment, the opening / closing contact mechanism is disposed close to the side of the housing 36 and the protruding pieces 22 are formed on both side surfaces of the button 21. Since the knurls can be uniformly processed on almost the entire upper surface, a wide range of illuminated surface can be obtained and an illuminating tilt switch excellent in design without shading inside the button 21 can be obtained.

FIG. 6 is an exploded perspective view showing a second embodiment of the illuminating tilt switch according to the present invention. As compared with the first embodiment, the projection 42 is provided on the filter 55 and the shielding plate 60 is
This is an example in which it is arranged on the lower surface of the ED 52.

By arranging the protruding piece 42 on the filter 55, the width of the filter 55 with respect to the button 41 can be widened.
Since there is no projection or the like that creates a shadow on the surface of the button 41 due to light from the button 41, a bright illumination surface with a uniform illumination state on the surface of the button 41 can be formed.

Since the shielding plate 60 is disposed on the lower surface of the LED 52, the LED 52 has a reflection effect, and an arc product such as carbon generated from the opening / closing contact portion at every opening / closing scatters on the button 41 and the filter 55. It also has the effect of preventing sooting and maintaining a clear illuminated surface for a long period of time.

In this embodiment, the shielding plate 60 is formed as a separate component, but may be formed integrally with the housing 56. Further, the shielding plate 60 can be fitted to the lower surface of the button 41 or the filter 55, and the arrangement means thereof is not particularly limited and may be any means.

The tilting shaft 3 and the tilting shaft 43 of this embodiment
Can be provided on the filter 15 and the filter 55, respectively. In this case, the button 1 and the button 41 can be attached and detached from above, and replacement of a character display film (not shown) and the like is facilitated. Further, the form and the number of the light-emitting members 12 are not limited, and multi-color light emission or a plurality of light-emitting members 12 can be provided.

(1) Since the opening / closing contact portion and the protruding piece of the button for driving the opening / closing portion are arranged along the side of the switch body, there is no projection inside the button that creates a shadow due to the light from the luminous body. Illuminating state is uniform and a vivid illuminating surface can be formed. (2) Since a filter made of a light-transmitting member is overlapped inside the button and the filter is provided with a protruding piece, the filter width for the button can be made wider, so that the illuminating surface is made wider. Can be. (3) Since a filter made of a light-transmitting member is overlaid inside the button and the protruding piece is provided on the filter, it is not necessary to cover the luminous body when using the transparent button. There is no need to provide an illuminating tilt switch having an excellent design such that characters can be displayed on buttons. (4) A shield is provided near the illuminator to prevent the arc product from scattering from the opening and closing contact to the inside of the button and the filter and to reflect the light of the illuminator toward the upper surface of the button.
