Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a click-type slide switch.

[Prior art]

FIG. 1 is a perspective view of a slide member 1 of a conventional slide switch, which is integrally molded from synthetic resin, with reference numeral 2 representing a knob and reference numeral 3 representing an elastic protrusion. Because this elasticity is necessary, the slide member 1 is made of expensive resin such as polyacetal.
When the slide member 1 is assembled into a case (not shown) and slides, the elastic protrusion 3 fits into a recess provided in the inner wall of the case, producing a click feeling. If the protrusion 3 is held in a position other than the above, the protrusion 3 will be pushed by the inner wall and bent, so the elasticity of the protrusion 3 will quickly wear out and the click feeling will become weaker, making it difficult to use for slide switches with long stroke pitches. There were flaws. Another disadvantage was that polyacetal was expensive and the material cost was high.

FIG. 2 is an exploded perspective view of the slide member 1 of another conventional slide switch, which is made of inexpensive synthetic resin such as polystyrene, with reference numeral 4 a spring, 5 a bearing, and 6 a hole. The one shown in Fig. 2 uses a spring compared to the one shown in Fig. 1, so there is less sagging, and inexpensive materials such as polystyrene can be used, but the bearings etc. are expensive.

[Purpose of invention]

The object of the present invention is to solve these drawbacks and provide a slide switch that is inexpensive and has an elastic protrusion with almost no wear.

[Key points of the idea]

In order to achieve the above object, the sliding member is provided with an auxiliary member, an elastic protrusion is provided at one end of the auxiliary member, a foot is provided at the other end, and a recess and a protrusion are provided in the case. The feet of the auxiliary member come into contact with the protrusions and move in a direction perpendicular to the sliding direction so that the elastic protrusions fit into the recesses, and have elasticity at positions where the feet do not come into contact with the protrusions. The protruding portion does not flex or is designed not to flex very much.

〔Example〕

FIG. 3 is an exploded explanatory view of one embodiment of the present invention, and parts similar to those in FIG. 1 are given the same numbers.

Reference numeral 7 denotes an auxiliary member that is inserted into the slide member 1, and has an elastic protrusion 7a at one end and a leg portion 7 at the other end.
b is provided. This auxiliary member 7 is inserted into the center of the auxiliary member 7 in the embodiment so that it can freely move in the direction perpendicular to the slide direction arrow x of the slide member 1 and move integrally with the slide member 1 in the slide direction. By making the width of the hollowed out part 9 of the part and the width of the fitting part 10 of the sliding member 1 with the auxiliary member 1 the same width a, they can move together, and the hollowed out width of the hollowed out part 9 in the direction perpendicular to the sliding direction b is the width c of the fitting part 10 of the slide member 1
By making it longer, it allows for more freedom of movement. In addition, the elastic protrusion 7 of the auxiliary member 7
The width d from the top of a to the lowest end of the foot 7b may be the same as the width e of the slide member 1, but the width d may be slightly longer than the width e. The width e is equal to the inner width f of the case 8. This is because if the width d is made slightly longer than the width e (width f), which is almost the same, the elastic protrusion 7a will be in a slightly bent state, and the stability of the auxiliary member 7 will be improved.

Further, the auxiliary member 7 is made of expensive polyacetal because it has an elastic protrusion 7a, but the slide member 1 can be made of inexpensive polystyrene, which is cheaper than the conventional ones shown in FIGS. 1 and 2. Can be done.

The case 8 has the sliding member 1 into which the auxiliary member 7 is inserted, and is formed with a recess 8a and a protrusion 8b.

Next, the operation will be explained. First, when the elastic protrusion 7a is located away from the recess 8a, the foot 7b is not in contact with the protrusion 8b, and the elastic protrusion 7a Since the protruding portion 7a does not bend or is only slightly bent, the protruding portion 7a, which has more elasticity than the conventional one, hardly wears out.

Next, as the slide member 1 slides, the auxiliary member 7 also slides, and as the foot portion 7b begins to come into contact with the projection 8b, the auxiliary member 7 begins to move in a direction perpendicular to the sliding direction. In the embodiment, the protrusion 8b has an arc shape, and the lowermost end of the foot 7b has a flat end shape, but this may be reversed, or both may be arc shaped, etc.
In short, any shape is sufficient as long as it allows the auxiliary member 7 to move smoothly. As the auxiliary member 7 slides and moves in the right angle direction, the elastic protrusion 7a approaches the recess 8a while gradually deflecting, and as it begins to enter the recess 8a, the deflection decreases, and when it is completely fitted into the recess, it does not deflect much. There isn't.

FIG. 4 is a partially omitted explanatory diagram showing the fitted state, and FIG. 4a is an example in which there are two legs 7b in this embodiment, and FIG. 4b is an example in which there are three legs 7b. , 4th
FIG. c shows an example in which the number of leg portions 7b is one. The number of leg portions 7b, the number of protrusions 8b, the number of recesses 8a, and their arrangement intervals may be determined as appropriate depending on the design.

[Effect of idea]

As explained above, the present invention provides an auxiliary support having an elastic protrusion 7a and a foot 7b that are fitted into the slide member 1 and can freely move in a direction perpendicular to the sliding direction of the slide member 1. Part 7
Since the case 8 is provided with a recess 8a and a protrusion 8b, the elastic protrusion has almost no sagging, can be used for slide switches with a long stroke pitch, and can be manufactured at low cost. have an effect.
