DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a slide switch.

[0002]

2. Description of the Related Art A slide switch having a plurality of circuits is used in various fields. FIG. 10 shows an example of the structure of the slide switch. FIG. 10 is a conceptual diagram of the structure of the slide switch 3 having a so-called two-circuit configuration. This slide switch 3 has terminals T11, T1
2, T13, and a slider 4p, and the circuit 2 includes terminals T21, T22, T23, and a slider 4q. Each of the sliders 4p and 4q is a conductor, and is fixed to a slide knob (not shown) via a portion serving as an insulating portion Z. That is, by operating the slide knobs, the sliders 4p and 4q are moved between the state shown in FIG. 10A and the state shown in FIG. 10B.

In the case of FIG. 10A, the terminal T11 and the terminal T12 are connected in the circuit 1, so that the signal system Sa1 in the circuit using the slide switch 3 is used.
And the common signal system COM1 is connected, and in the circuit 2, the terminal T21 and the terminal T22 are connected, so that the signal system Sa2 and the common signal system COM2 are connected.
On the other hand, in the state of FIG. 10B, the terminal T13 and the terminal T12 are connected in the circuit 1, so that the signal system Sb1 and the common signal system COM1 in the circuit using the slide switch 3 are connected. 2, terminal T
When the terminal 23 is connected to the terminal T22, the signal system Sb2 and the common signal system COM2 are connected. The slide type switch 3 switches the signal paths that are linked by two circuits.

FIG. 11 shows a switch circuit structure in which a slide switch 5 and a push switch 6 each having one circuit configuration are combined. The slide switch 5 has terminals T11, T12, T13, and a slider 7, thereby forming a signal path switch. The slider 7 as a conductor is fixed to the slide knob 8, and when the slide knob 8 is operated, the slider 7 is moved between the state shown in FIG. 11A and the state shown in FIG. It is moved by. That is,
In the case of FIG. 11A, the terminals T11 and T12 are connected to connect the signal system Sa1 and the common signal system COM1, and in the state of FIG. 11B, the terminals T13 and T12 are connected and the signal system is connected. Sb1 is connected to the common signal system COM1.

On the other hand, the push switch 6 has a terminal T
31 and T32, a switch 9 made of a conductor, and a presser 10 are provided. For example, the switch 9 and the presser 10 are urged in the direction of the arrow F by some urging means 12 and 11, respectively. Therefore, in the state of FIG. 11A, the switch 9 is opened and the terminals T31 and T32 are opened. The connection is disconnected. Here, the pressing element 10 is arranged such that the top is located on a slide path of a part of the slide knob 8, and accordingly, FIG.
When the slide switch 5 is operated as in 1 (b), the slide knob 8 presses the pusher 10 in the direction of the arrow P. At this time, the other end of the pressing element 10 presses the switching element 9, whereby the switching element 9 is connected to the terminals T31 and T3.
The two are electrically connected. In the switch configuration as shown in FIG. 11, the connection of the signal systems Sa3 and Sb3 can be turned on / off by the push switch in conjunction with the switching of the signal path by the slide switch 5.

[0006]

In the slide switch 3 having a plurality of circuits as shown in FIG. 10, since both circuits are operated in conjunction with each other to switch the signal system, in addition to switching the signal system to be operated in the circuit, For example, the circuit 1 can be used for switching the signal path, and the circuit 2 can be used for detecting the state of the signal path in the circuit 1. By the way, for example, when a signal path is switched, there may be a case where it is desired to detect that the signal path is switched immediately before the switching timing of the signal path. For example, if you want to perform some processing in accordance with the signal path switching timing,
When there is a situation in the operation of the device, it is desired to detect the switching immediately before the switching is actually performed. However, in a normal slide switch as shown in FIG.
Are switched almost simultaneously, and one of the circuits cannot be used for the above detection operation. Further, without being limited to the detection operation, there may be a case where switching or opening and closing of the signal path in the circuit 1 and switching or opening and closing of the signal path in the circuit 2 are desired to be performed at slightly different timings. Is not suitable.

On the other hand, by combining a plurality of switches such as a slide switch 5 and a push switch 6 as shown in FIG. 11, it is possible to perform interlocked switching with slightly shifted timing. However, in this case, a plurality of switches inevitably increase the number of components and complicate the configuration. In addition, in order to actually perform interlocking switching and slightly shift the timing, the arrangement relationship of the switches and the interlocking mechanism ( The precision of the slide knob 8, the presser 10) and the like is strictly required. However, accuracy errors in mounting the switches on a circuit board, a chassis, or the like are unavoidable to some extent, and it is likely that the interlocking of the switches does not work well.
Conversely, high precision is required for the switch mount, which makes it difficult to manufacture devices.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the foregoing problems, and has been made in view of the above-mentioned problems. A slide switch in which the switching timing at the second terminal portion by the second slider accompanying the sliding of the second terminal is different from the switching timing. This realizes a more versatile use of a slide switch capable of interlocking switching or opening and closing of a plurality of circuits, and does not cause complication of the configuration or difficulty in manufacturing devices. The first terminal portion is configured to switch a signal path by switching a terminal connection state by moving the first slider, and the second terminal portion is configured to switch a terminal by moving the second slider. It is preferable that the signal path is opened and closed by switching the connection state, so that the first circuit is used for switching the signal system, and the second circuit is used as the detection circuit system for the signal switching state. And

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, various examples of structures of a slide switch according to an embodiment of the present invention will be described. 1 to 7 are described as models of the switch structure, and examples of the actual switch structure will be described with reference to FIGS. FIG. 1 shows a slide switch 20 provided with a circuit for switching one signal path and a circuit for switching one signal path. In this case, the circuit for switching a signal path is replaced with a circuit for switching a signal path. This example is used as a detection circuit of a switching state in a circuit.

The slide switch 20 includes terminals T21, T22, and T23 for switching a signal path, a slider 21 as a conductor, and a terminal T2 for a signal path switching circuit.
4, T25, and a slider 22 as a conductor. The sliders 21 and 22 are fixed to the slide knob 23 and are slid simultaneously with the operation of the slide knob 23. The slider 21 is moved from a position in contact with the terminals T21 and T22 as shown in FIG. 1A in the sliding range of the slide knob 23 to a terminal T2 as shown in FIG.
2. Displaced until it is in contact with T23. Slider 2
FIG. 2 shows a state in which the slide knob 23 slides in FIG.
The position is displaced from the position where it is not in contact with any terminal as shown in FIG. 1A to the state where it is in contact with terminals T24 and T25 as shown in FIG.

Here, the sliding distance from the state where the slider 21 is in FIG. 1A to the position where the terminals T23 and T22 are connected is x, and the slider 22 is in the state shown in FIG. Is set such that x> y in this case, where y is the sliding movement distance from the position to the position where the terminals T24 and T25 are connected. Therefore, the switching timing in the signal path switching circuit when the slide knob 23 is slid and the opening / closing timing in the signal path switching circuit are slightly different.

That is, the terminal T2 is used as a signal path switching circuit.
1 and T22 are connected, and the slide knob 23 is operated from the state of FIG. 1A in which the terminals T24 and T25 are off as a signal path switching circuit to the state of FIG. 1C. At a certain slide position in FIG.
The state shown in (b) is obtained. This FIG. 1 (b)
At a timing before the connection between the terminals T22 and T23 is made, the connection between the terminals T24 and T25 has already been completed. As described above, after the terminals T24 and T25 are connected first and the signal path switching circuit is turned on, FIG.
, The signal path switching circuit is switched to the state in which the terminals T22 and T23 are connected, and the signal path switching circuit is turned on. That is, in the slide switch 20, when the state shown in FIG. 1A is switched to the state shown in FIG. 1C, the signal path switching circuit is turned on first, and then the signal path switching circuit is switched. Is performed.

By using this mechanism, the switching of the signal path switching circuit can be detected at a timing earlier than the switching by using the signal path switching circuit as a detection circuit. Now
It is assumed that the signal system Sa is connected to the terminal T21, the terminal T22 is used as the common signal system COM, and the signal system Sb is connected to the terminal T23. Here, the signal system Sa and the common signal system C
When the signal system Sb and the common signal system COM are connected from the state where the OM is connected (FIG. 1A), there is a need to execute a certain process or the like. Immediately before the signal COM is connected, it is assumed that there is a situation in which the switching is to be detected. At this time, for example, a predetermined potential is applied to the terminal T24 via the resistor r, and the potential point 2
4 is supplied to, for example, a microcomputer or other detection control circuit parts. On the other hand, the terminal T25 is grounded.

Then, the switching timing of the signal systems Sa and Sb and the state of the terminal T24 (potential point 24) are as shown in FIG. That is, in the state of FIG. 1A, the signal system Sa is selected for the common signal system COM, and the terminal T2
4, a predetermined potential (H level) is maintained, but as shown in FIG. 1B, the terminals T24 and T25
Since the terminal T24 is grounded at the time when is connected, FIG.
At the time point TM1, the potential of the terminal T24 falls to the L level.
Thereafter, at time TM2 when the state shown in FIG. 1C is reached, the state is switched to the state in which the signal system Sb is selected for the common signal system COM.

Therefore, since the detection control circuit system monitors the potential level of the potential point 24, the signal system Sb can be detected immediately before the signal system Sb is selected. For example, during the period between TM1 and TM2 in FIG. , A predetermined process for preparing the connection of the signal system Sb can be executed. Moreover, it is not necessary to prepare another switch as described with reference to FIG. 11 for such immediately preceding detection, so that the configuration can be simplified, and the instability of operation due to mounting accuracy errors. Can be eliminated.

The slide switch 30 shown in FIG. 3 is an example for realizing a timing shift opposite to that of the example shown in FIG. The slide switch 30 includes terminals T21, T22, T23 and a conductor 31 serving as a conductor, and terminals T24, T25 and a terminal T24, T25 constituting a signal path switching circuit, as in the example of FIG. It has a slider 32 that is a conductor.
The sliders 31 and 32 are fixed to a slide knob 33 and are slid simultaneously with the operation of the slide knob 33. The slider 31 contacts the terminals T22 and T23 as shown in FIG. 3C from a position where the slider 31 is in contact with the terminals T21 and T22 as shown in FIG. 3A, the slider 32 is moved from the position where it is not in contact with any terminal as shown in FIG. 3A to the terminal T2 as shown in FIG.
4. Displaced until it comes into contact with T25.

In this example, the slider 31 moves from the state shown in FIG. 3 (a) to the position where the terminals T23 and T22 are connected, and the slider 32 moves from the state shown in FIG. The slide movement distance y to the position where T24 and T25 are connected is set such that x <y. For this reason, the terminals T21 and T21 serve as signal path switching circuits.
22 is connected, and a terminal T is used as a signal path switching circuit.
In the process in which the slide knob 23 is operated from the state of FIG. 3A in which the interval between 24 and T25 is off to the state of FIG. 3C, the slide knob is shown in FIG. 3B at a certain slide position. The state is obtained.

FIG. 3B shows the timing before the terminals T24 and T25 are connected and the terminals T22 and T25 have already been connected.
23 has been completed. As described above, after the terminals T22 and T23 are first connected and the signal path switching circuit is switched, the terminals T24 and T25 as the signal path opening / closing circuits are slid to the state shown in FIG.
Is connected. That is, in the slide switch 30, when the state shown in FIG. 3A is switched to the state shown in FIG. 3C, the signal path switching circuit is switched first.
Thereafter, the signal path switching circuit is turned on.

Here, the signal system Sa is connected to the terminal T21, the terminal T22 is used as the common signal system COM, the signal system Sb is connected to the terminal T23, and the signal systems Sa and Sb are selected for the common signal system COM. Configuration. On the other hand, the signal system Sc is connected to the terminal T24, the signal system Sd is connected to the terminal T25, and the connection of the signal systems Sc and Sd is opened and closed.

The switching timing difference between the signal path switching circuit and the signal path switching circuit in this case is as shown in FIG. That is, in the state of FIG. 3A, the signal system Sa is selected for the common signal system COM, and the terminals T24 and T25 are in a non-contact state and are off between the signal systems Sc and Sd. Assuming that the state shown in FIG. 3B is reached at time TM1, the state is switched to the state in which the signal system Sb is selected for the common signal system COM. Thereafter, at the time point TM2 when the state shown in FIG. 3C is reached, the signal lines Sc and Sd are turned on.

As can be seen from this operation, the slide switch 30 is suitable for a case where the switching timing of the signal path switching circuit and the switching timing of the signal path switching circuit are to be slightly shifted.

Each of the sliders 41, 42, and 43 is displaced from the position shown in FIG. 5A to the position shown in FIG. 5C in the sliding range of the slide knob 44.

In this case, when the slider 41 (slider 42) is in the state shown in FIG.
5 (a) from the state shown in FIG.

6. At the timing before the connection of T27 is made, the connection of the terminals T24 and T25 is completed first. That is, in the slide switch 40, the state shown in FIG.
When the state is switched to the state (c), the signal path switching circuit is turned on first, and thereafter each of the two signal path switching circuits is switched.

For example, by using a signal path switching circuit including terminals T24 and T25 and a slider 43 as a detection circuit as shown in FIG. 1, the switching state of the two signal path switching circuits can be changed.
It can be detected first with a slight timing difference.

FIG. 6 shows an example of a slide switch 50 having a circuit for switching two signal paths and a circuit for opening and closing one signal path as in FIG. That is, the slide switch 50 is connected to the terminal T2 which constitutes a signal path switch.

In this case, when the slider 51 (slider 52) is in the state shown in FIG.
6A, and the slider 53 moves from the state of FIG. 6A to the terminal T2.
Slide movement distance y to the position where 4 and T25 are connected
Are set so that x <y. Therefore, from the state of FIG.
In the process of operating up to the state of (c), the state shown in FIG. 6B is obtained at a certain slide position, that is, the connection of the terminals T22 and T23 and the connection of the terminals T26 and T27 are performed. T24 and T25 are not connected. Thereafter, the terminals T24 and T25 are connected in the state of FIG. 6C. Thus, in the slide switch 50, the switching timing of the two signal path switching circuits is earlier than the timing at which the signal path switching circuit is turned on.

FIG. 7 shows a slide switch 60 having four signal path switching circuits and one signal path opening / closing circuit. That is, the slide switch 6
0 denotes a terminal T21, T22, T23 and a slider 61 as a conductor, terminals T26, T27, T28 and a slider 62 as a conductor, and terminals T31, T32, T33 and a slider 63 as a conductor. , Terminals T34, T35, T36 and a slider 64 as a conductor constitute four signal path switching circuits. Further, it has terminals T24 and T25 constituting a signal path switching circuit and a slider 65 as a conductor. The sliders 61, 62, 63, 64, 65 are fixed to the slide knob 66, and are slid simultaneously with the operation of the slide knob 66. Each slider 6

In the process of operating up to the state of (c), the state shown in FIG. 7B is obtained at a certain slide position, that is, the terminals T23 and T22, the terminals T26 and T27, and the terminal T31.
At the timing before the connections between the terminals T32 and T32 and between the terminals T34 and T35 are made, the connection between the terminals T24 and T25 is completed first. That is, in the slide switch 60, FIG.

As can be seen from FIG. 8B, the sliders 62 and 64 (similarly to the sliders 61 and 63) are each formed of an elastic metal piece having a shape having two protrusions toward the terminal side. For example, in FIG. 8B corresponding to the slide position state of FIG. 7A, two protrusions of the slider 62 are connected to the terminal T2.

Although various embodiments have been described above,
Various other examples of the slide switch of the present invention are conceivable. In each of the examples, the switching of the portion as the signal path switching circuit and the opening and closing of the portion as the signal path switching circuit are performed at different timings. A circuit is also conceivable. That is, this is an example in which a certain signal path switching circuit and another signal path switching circuit are interlocked and switched at different timings. Conversely, in this example, the signal path switching circuit having the two-terminal configuration and the other signal switching circuits are interlockedly opened and closed at different timings. In this case, a switch configuration in which one is turned on and the other is both turned on, or a switch configuration in which one is turned on and the other is turned off is possible.

[0032]

As described above, the slide switch according to the present invention is capable of controlling the switching timing at the first terminal portion by the first slider accompanying the slide of the slide operator, and also the slide of the slide operator. Since the switching timing at the second terminal portion by the second slider is different from the switching timing, it is very suitable as a switch in the case where it is desired to make the switching timing slightly different from the switching timing. Become. In addition, since interlocked switching with different timings can be performed as one switch component, operation instability due to a mounting error or a complicated circuit configuration is not caused, and stable operation can be provided with low cost and simplified manufacturing. This has the effect. Further, the first terminal portion is configured such that a signal path is switched by switching a terminal connection state by movement of the first slider.
The second terminal section is configured to open and close the signal path by switching the terminal connection state by moving the second slider, so that the second circuit can connect the signal in the first circuit system. It is suitable for use as a system switching state detection circuit system and the like, and can be applied in various fields.
