Description

[Detailed description of the invention] The present invention relates to a switch that can turn on and off the contact multiple times with a single push operation.In particular, when the operating knob is rotated and the push operation is performed, the switch stroke changes and the switch is turned on and off multiple times with one push operation. The present invention provides a switch that can change the number of on-off operations of a contact by a push operation.

Conventional push-on switches turn the contacts on and off simply by moving the knob back and forth, while rotary switches turn the contacts on and off simply by rotating the knob. I was doing it.

However, with such a switch that has only one degree of freedom of movement, it is difficult to perform variable operations at the switch portion.

The present invention provides a push-on switch that can be operated in a wide variety of ways by providing rotational freedom.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a sectional view of a switch in an embodiment of the present invention.
FIG. 2 is a perspective view of the switch.

In these figures, 1 is a shaft with tips 1a and 1b, 2
Knob 3 has protrusions 3a and 3b, recesses 3C and 3d at one end, and a hole 3 inside.
e, a cylindrical case having a cavity 3f and a terminal plate 3g; 4, a sliding piece made of an insulator; 5, a spring; 6, a U-shaped contact piece; 7, a contact insulating board that contacts the contact piece 6; Terminals 8a and 8b are drawn out from the terminal plate 3g.

FIG. 3 is a plan view when the U-shaped contact piece 6 is in contact with the contact insulating substrate 7, where 9.10 is the contact portion of the U-shaped contact piece 6 made of a conductor, and 11 is the contact portion. 12 is a rectangular electrode that is in constant contact with the contact portion 9; 12 is a comb-shaped electrode that comes into contact with and separates from the contact portion 10; 12 a, 12 b, 12 C, 12 d;
Teeth portions 13 and 14 of the comb-shaped electrode 12 are lines indicating positions on the contact insulating substrate 7.

A knob 2 is firmly fitted to the tip 1a of the shaft 1, and in conjunction with this knob 2, the shaft 1 moves in the axial direction along the hole 3e and rotates around the axis.

The vicinity of the tip 1b of the knob 2 is inserted into the hole 3e of the case 3, so that the knob 2 can freely move in the direction of penetration of the hole 3e.

Further, the diameter of the tip 1b is larger than that of the other portions so that it does not slip out of the hole 3e.

In the cavity 3f of the case 3, there are a sliding piece 4, a spring 5, a contact piece 6,
The sliding piece 4 in which the contact insulating board 7 is housed is in contact with the tip 1b of the shaft 1 on one side, and is pressed by a spring 5 on the other side, so that the shaft 1 is moved in the axial direction along the hole 3e. It moves as it moves.

One end of the spring 5 is held down by the terminal plate 3g so that it does not come out.

A contact piece 6 is provided on the lower surface of the sliding piece 4, and as the sliding piece 4 moves, the contact portion 9 of the contact piece 6 shown in FIG. Part 10
The electrodes 12a to 12d move toward and away from the teeth of the comb-shaped electrode 10.

The rectangular electrode 11 is provided with a terminal 8a, and the comb-shaped electrode 1
2 is provided with a terminal 8b.

The contact piece 6 is made of a U-shaped conductor and has two contact parts 9 and 10 that move while contacting the contact insulating substrate 7.

The end of the case 3 facing the knob 2 has a protrusion 3 a ,
3b and recesses 3C and 3d are provided.

Further, the knob 2 is provided with flanges 2a and 2b.

Next, the switch operation of the above structure will be explained.

As shown in Fig. 1 and Fig. 2,
and 2b are facing the convex parts 3a and 3b of the case 3, respectively, and when the knob 2 is pushed with a finger in the direction of the arrow A, the shaft 1 moves in the axial direction along the hole 3e in conjunction with the knob 2, At the tip 1b, the sliding piece 4 is pushed and moved toward the terminal plate 3g against the force of the spring 5.

Then, the contact piece 6 provided on the sliding piece 4
In the figure, the contact portion 9 moves in the direction of arrow A, and the contact portion 9 moves toward the terminal 8a while contacting the rectangular electrode 11.

On the other hand, the contact portion 10 is a tooth portion 12 3 of the comb-shaped electrode 12.
It moves toward the terminal 8b while moving toward and away from the terminal 8b.

The movement of these contact parts 9 and 10 is such that the collar 2a of the knob 2 comes into contact with the convex part 3a of the case 3 in FIGS. 1 and 2, and
The first stop occurs when the second part 2b comes into contact with the convex part 3b.

The brim 2a and 2b abut the convex portions 3a and 3b, respectively,
The length of the shaft 1 and the comb-shaped electrode 1 are adjusted so that the contact portions 9 and 10 stop at the position shown in FIG. 3 and line 13.
The positions of the second tooth portions 12a to 12d are set in advance.

In this case, the contact part 10 first contacts the toothed part 12a and then comes into contact with the toothed part 12b and then separates and stops operating. There are 2 on-off operations between 8a and 8b.
It will be rotated.

Next, when the knob 2 is pressed and then released from the stopped state, the sliding piece 4 is pushed back toward the hole 3e by the spring 5.
Return to the original state.

Next, in FIGS. 1 and 2, the knob 2 is rotated about the axis 1 in the direction of the arrow B, and the knob 2 is turned so that the collar 2a faces the recess 3C and the collar 2b faces the recess 3d. Push in the direction of arrow A.

In this case, since the ribs 2a and 2b can move until they come into contact with the recesses 3C and 3d, the contact portions 9 and 10 of the contact piece 6 in FIG. Stop.

Therefore, in this case, one push operation of the knob 2 causes the contact portion 10 to contact the four tooth portions 1 of the comb-shaped electrode 12.
Since the terminals 2a to 12d are connected to and separated from each other, the on-off operation between the terminals 8a and 8b is performed four times.

As before, when you press the knob and release your finger, the switch returns to its original state.

Note that the switching of the number of on-off operations between the terminals 8a and 8b by rotation of the knob 2 is not limited to two stages, and can be performed by changing the number and shape of the flanges 2a, 2b of the knob 2, or the end surface of the case 2 facing the knob 2. Switching can be performed three or more times by changing the shape of the concavo-convex portion.

For example, as shown in FIG.
, 2b, there are uneven parts 15a and 1
5b, 16a and 16b, and 17a and 17b are provided in three stages.

In the same figure, for example, when the ribs 2a and 2b abut the first protrusions 15a and 15b, the number of on-off cycles between the terminals 8a and 8b is reduced to one by one push operation of the knob 2. The comb-shaped electrode 12 shown in FIG.
The cutting pitch, the length of the shaft 1 in FIG. 1 or 2, or the height of the convex portions 15 a and 15 b are designed.

In addition, when the brim 2a and 2b abut the second convex portions 16a and 16b, the terminal 8a is removed by a push action.
The number of on-off operations between terminals 8a and 8b is set to, for example, two times, and when the ribs 2a and 2b abut on the recesses 17a and 17b, respectively, the number of on-off operations between terminals 8a and 8b is set to, for example, four times by push operation. You can design a switch.

There are various possible uses for such a switch, but for example, if it is used as a switch in the recently popular Invader game, the player can make many changes, such as changing the number of rockets fired just by operating a single switch. You can enjoy the game.

As explained above, the switch of the present invention has the feature that it can be operated in a variety of ways despite its simple structure.
