Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a tilting switch, and in particular, the present invention provides a light snap-action switch that utilizes a concave-convex engagement between a bent part provided on an elastic plate and a recess formed in a protruding part. This invention relates to a small tilting switch that can provide a high degree of movement.

(Summary of the invention) In order to obtain a light operating feeling especially in a small switch, this invention provides an elastic plate on either the bottom surface of the switch body or the lower part of the handle, and a protrusion on the other side, so that the tilting of the handle To provide a small tilting switch that provides a light snap action.

(Prior art) Conventionally, this type of switch has a guide provided in the handle, a slider inserted through a coil spring, and a chevron-shaped switching plate corresponding to the slider. The structure was such that the slider slid along with the switch to obtain switching moderation.

Also, the mountain-shaped switching plate was not only provided as a separate part, but also one that was formed integrally with the base.

(Problems to be solved by the invention) Since the conventional switch described above uses a slider and a switching plate, the width of the main body on the side in the switch operation direction inevitably increases. However, due to wear, the deflection of the coil spring decreases, resulting in a light operating feel, and the rough surface causes a poor operating feel. In addition, when miniaturizing the coil spring, the coil spring must be made very small, and problems such as load and fatigue have caused difficulties in its design.

(Means for Solving the Problems) The small tilting switch of the present invention has an elastic plate that is approximately U-shaped and has bent portions at both ends on either the inner bottom surface of the switch body or the inner bottom surface of the handle, and the elastic plate on the other side. providing a protruding portion having a recess that engages with the bent portion;
A snap action can be obtained by tilting the handle left and right.

(Function) According to the present invention, the bent portions provided at both ends of the elastic plate engage with the recesses provided in the protruding portion, and by tilting the handle, the left and right uneven engagements are released alternately, and the snap You can get action.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 5 is a perspective view of the handle of the present invention.

In the figure, switch body 1 is formed by combining 2. 3 is a protrusion provided from the center of the inner bottom surface of the switch body 1, 4 is a recess provided on the left and right side surfaces above the protrusion 3, 5 is a fixed contact piece, 6 is a movable contact piece, and 7 is an elastic contact piece. 8 is a bent portion provided at both ends of the elastic piece 7, 9 is a hole for attaching it below the handle, 10 is a handle, 11 is a shaft provided on the front and rear sides of the handle 10, and 12 is provided below the handle. , a rectangular hole for mounting a movable contact piece, and 13 a recess formed below the handle 10.

As shown in these figures, the switch body 1 is box-shaped, has an opening at the top, and is vertically divided.
A fixed contact piece 5 is disposed on the inner surface by insert molding or the like, and a terminal piece 14 is formed to protrude from the lower surface of the switch body. Furthermore, there is a protrusion 3 with recesses 4 formed on the upper left and right sides of the bottom surface of the switch main body.
It is provided by an uneven relationship. In the embodiment of the present invention, it is a separate component, but it may be formed integrally. There are stepped sections 1 on the left and right sides of the inner bottom of the switch body.
5 is formed, and this stepped portion 15 serves as a stopper for regulating the tilting range of the handle 10. A cylindrical shaft 11 protrudes from the front and rear sides of the handle 10.
A recess 13 is provided on the lower surface of the recess 13, and a protrusion 16 is formed in the center of the recess 13. The elastic plate 7 has a U-shape and has bent portions 8 at both ends, and has a hole 9 approximately in the center into which a protrusion 16 formed at the center of the lower surface of the handle 10 can be inserted. elastic plate 7
to fix. Various methods of fixing the elastic plate 7 can be considered, such as insert molding, and are not limited to this embodiment. A square hole 12 is provided in the lower surface of the handle 10, and a movable contact piece 6 formed of an elastic plate that opens and closes the switch and comes into sliding contact with the fixed contact piece 5 is attached. The fixed contact pieces 5 are short-circuited by tilting the handle 10 from side to side. The handle 10 is a hole 1 provided on the inner surface of the switch body 1.
A shaft 11 is fitted into the shaft 7 to make it freely tiltable. With the above configuration, the bent portions 8 of the elastic plate 7 are alternately engaged with the recesses 4 of the protruding portion 3 by the tilting of the handle 10, and a snap action is obtained by utilizing elasticity.

In this embodiment, the switch body 1 is formed by combining the cases 1 and 2, and they are fixed together using an adhesive, an ultrasonic welder, or the like.

FIG. 6 shows a second embodiment of the present invention, in which the handle 10 can be stopped at the center position depending on the positional relationship between the bent part 8 of the elastic plate 7 and the recess 4 of the protruding part 3. . 2 each on the left and right sides above the protrusion 3.
Recesses 4a and 4b are provided at two locations, and the handle 10 is held at its center by engaging with a bent portion 8 provided on the elastic plate 7.

FIG. 7 shows a third embodiment of the present invention. The left and right sides of the switch body 1 are made smaller and the handle 10 is covered. In this embodiment, in order to provide a square hole 12 for attaching the movable contact piece 6, it is necessary to provide a piece (not shown) hanging down from the recess 13 of the handle 10.

In the embodiment of the present invention, the elastic plate 7 is provided on the handle 10 side and the protrusion 3 is provided on the switch body 1 side, but conversely, the protrusion 3 is provided on the handle 10 side and the elastic plate 7 is provided on the switch body 1 side. You may do so.

Further, the present invention is not limited to the above embodiments, and various modifications can be made based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

(Effects of the invention) As described above in detail, according to the invention, the following effects can be achieved.

(1) According to the present invention, the bent portions formed at both ends of the elastic plate and the recesses provided in the protruding portion engage alternately on the left and right sides when the handle is tilted, so the number of parts is small and the structure is simple. , a small tilting switch with a light snap action is obtained.

(2) Unlike the structure that uses conventional coil springs, even when downsized, a safe elastic plate can be designed that does not cause the spring to fatigue, resulting in a long service life with no change in operating feel or operating force. A small tilting switch is obtained.

(3) According to the present invention, since the bent portions formed at both ends of the elastic plate and the recesses provided in the protrusion are engaged alternately on the left and right sides by tilting the handle, it is possible to change the engagement position. As a result, the tilting position of the handle can be arbitrarily obtained, and therefore a small tilting switch can be provided that is suitable for the purpose and design of the device.

(4) According to the present invention, the protrusions formed at both ends of the elastic plate and the recesses provided in the protrusion engage alternately on the left and right,
Since the structure is such that the movable contact piece and the fixed contact piece are in sliding contact, a small tilting switch having a snap action with high contact reliability can be obtained.

(5) According to the present invention, unlike the conventional structure in which sliders are inserted through coil springs, an elastic plate is used, so even if the elastic plate is quite thin,
Since the safety against fatigue etc. can be ensured, the space can be reduced compared to a coil spring, and the width of the switch body can therefore be reduced.
