And a case 9 for holding the case 9 in a state where it can move freely.

More specifically, in this embodiment, one electrode 4L, the common electrode 4C, and the other
R is arranged linearly. Among them, for example, a combination of one electrode 4L and the common electrode 4C forms an open end of one circuit, and a combination of the other electrode 4R and the common electrode 4C forms an open end of the other circuit. Mounted on a printed wiring board. Each contact 5 forming the contact conductor 5
The distal ends of L, 5C, and 5R are each formed in an arc shape, and are prevented from being caught when the substrate surface is slid. In the present embodiment, the shape of the slider 8 is convex, and the convex portion is taken out and protrudes from the window of the case 9 to the outside as 7. Here, the distance between the common electrode 4C and each of the electrodes 4L and 4R and the distance between each contact 5
L, 5C, 5R, and the sliding surface 3L,
The lengths of 3C and 3R may be appropriately set according to the connection function provided to the DIP switch 1. For example, two open ends may be simultaneously short-circuited.

Next, the overall operation of this embodiment will be described with reference to FIGS.

Then, slide 7 so that the common electrode 4C
And the open end formed by the one electrode 4L or the open end formed by the common electrode 4C and the other electrode 4R is used. FIG.
Shows a state where both open ends are not short-circuited, and FIG.
This shows a state where the open end formed by the common electrode 4C and the other electrode 4R is short-circuited.

Further, various connection states are shown based on FIG. In the following description, the common electrode 4C and the one electrode 4
The open end formed by L is called one open end, and the open end formed by the common electrode 4C and the other electrode 4R is called the other open end.

In the sliding position of the slider 8 in FIG. 3A, one of the open ends is not short-circuited to the other. At the sliding position of the slider 8 in FIG. 3B, only the other open end is short-circuited. At the sliding position of the slider 8 in FIG. 3C, only one open end is short-circuited. At the sliding position of the slider 8 in FIG. 3D, one of the open ends is not short-circuited at the other end.

As described above, according to the present embodiment, one open end and the other open end can be individually short-circuited according to the sliding position of the slider, so that two DIP switches are conventionally required. Can be compensated for by a single DIP switch, so that the area occupied by the DIP switch on the printed wiring board can be reduced as compared with the conventional example, and the size of the device using the printed wiring board can be reduced. Can also contribute. Further, in the present embodiment, the one electrode, the common electrode, and the other electrode are arranged in a straight line, so that the case volume of the DIP switch can be minimized, and the size of the DIP switch itself can be reduced. Occupied area can be further reduced.

Next, another embodiment of the present invention will be described with reference to FIGS.

In the DIP switch 1 shown in FIG. 4, the length of the common contact 5C is equal to the sliding surface 3 of the common electrode 4C in the normal state.
It is set short so as not to contact C. Other configurations are the same as those of the above-described embodiment. Here, one contact 5L and the other contact 5R of the contact conductor are provided.
Have a leaf spring action to push the slider 8 back to the inner surface of the case. Then, after the contact conductor 5 is slid to a predetermined position on the substrate 2 by operating the handle 7, when the slider 8 is further pushed in the direction of the substrate,
The tip of the common contact 5C of the contact conductor 5 contacts the sliding surface 3C of the common electrode 4C, and the open end is short-circuited.

This will be described with reference to FIG.
In the sliding position of the slider 8 in FIG.
Is pushed into the substrate side, and one open end of the other is not short-circuited. Slider 8 in FIG.
When the slider 8 is pushed toward the substrate at the sliding position of
Only the other open end is short-circuited. In the sliding position of the slider 8 in FIG. 5C, when the slider 8 is pushed toward the substrate, only one open end is short-circuited. In the sliding position of the slider 8 in FIG. 5D, even if the slider 8 is pushed in, the open ends of one and the other are not short-circuited.

As described above, according to the present embodiment, the same operation and effect as those of the above-described embodiment are obtained, and the common contact 5C of the contact conductor 5 is set to be short so as not to contact the common electrode in a normal state. By pressing the slider, instantaneous on / off operation of the switch can be realized.

[0022]

Since the present invention is constructed and functions as described above, according to this, one open end and the other open end can be individually short-circuited according to the sliding position of the slider, so that the conventional In this case, the need for two DIP switches can be compensated for by one DIP switch, which can reduce the area occupied by the DIP switches on the printed wiring board as compared with the conventional example. This can contribute to miniaturization of a device using a wiring board.

In particular, when the common contact of the contact conductor is in a normal state
The slider is set short so that it does not contact the common electrode.
To switch on and off instantaneously.
Work can be realized.

According to the second aspect of the present invention, one of the electrodes is shared.
Since the through electrode and the other electrode are arranged in a straight line,
The case volume of the switch can be minimized, and D
By reducing the size of the IP switch itself,
, It is possible to provide an unprecedented excellent DIP switch that can reduce the occupied area of the DIP switch.
