DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch device using a switch element having a contact by being pressed against a contact.

[0002]

2. Description of the Related Art Heretofore, a switch device using a switch element in which electrical switching is performed by pressing a contact arranged opposite to a contact has been used.

A switch element used in this type of switch device is provided with a contact facing and separate from the contact. The contact is urged by a spring in a direction away from the contact, is pressed against the urging force of the spring, contacts the contact, and is released from the contact when the pressing is released.

This switch device is provided with an operation member for pressing a contact of a switch element.
This operating member is integrally connected to the operating element of the switch element.

A switch device having such a configuration is
When the operating member is pressed, the contact is pressed against the urging force of the spring and comes into contact with the contacts, thereby achieving electrical continuity between the contacts. Performs electrical switching.

[0006]

In the switch device constructed as described above, since the operating member is integrally connected to the contact of the switch element, the moving stroke of the operating member is limited by the moving amount of the contact. Depends on. Therefore, the movement stroke of the operation member cannot be freely changed.
Further, the operation member is provided for the purpose of operating the switch element from a separated position, and is formed longer than the moving amount of the contact.

[0007] The switch element, in which the contact is brought into contact with and separated from the contact, is formed in a small size in order to reduce the storage space. Therefore, the amount of movement of the contact in the direction in which the contact comes into contact with and separates from the contact is also small.

Incidentally, in the switch device, in order to perform a reliable switching operation of the switch element, it is desirable that the user surely senses that the operation member has been pressed. If it is not sufficiently sensed that the operation member has been moved, the user must repeatedly operate the operation member, and cannot perform the switching operation of the switch element as desired.

As described above, in the switch device in which the operating member is connected to the contact having a small moving amount so as to move integrally, the moving stroke of the operating member is small.
It is difficult for the user to reliably detect the state in which the operating member is pressed, and there is a possibility that a desired switching operation cannot be performed reliably.

Further, in the switch device in which the operating member is connected to the contact of the switch element so as to move integrally, the operational feeling when the operating member is pressed is determined by a spring for biasing the contact. Depends on bias. For example, the pressing force when the operating member is pressed and the state of the load during the pressing operation depend on the biasing force of the spring that biases the contact. For this reason, it is difficult to change the operational feeling when the operating member is pressed in accordance with the size of the switch device, the size of the operating member, and the like.

It is an object of the present invention to provide a switch device which enables a reliable switching operation of a switch element.

Another object of the present invention is to provide a switch device which has a good operability by changing a moving stroke of an operating member for pressing a contact without being restricted by a moving amount of the contact of the switch element. Is to do.

It is a further object of the present invention to provide a switch device which enables a plurality of switching operations with one operation member.

It is still another object of the present invention to provide a switch device which can reduce the size of the device itself.

[0015]

A switch device according to the present invention proposed to achieve the above object has a switch element which can be switched by being pressed, and a retractable support for pressing the switch element. Operation member provided. And, by interposing a first urging member such as a coil spring between the switch element and the operation member, the movement stroke of the operation member is enlarged.

As the biasing member, a member having a spring constant capable of pressing the switch element after the operation member is moved by a predetermined amount is selected.

Therefore, by appropriately selecting the biasing member, the moving stroke of the operating member for switching the switch element can be freely set, and the pressing force when operating the operating member can be selected.

The operating member supported by the switch element so as to be able to advance and retreat is moved in a direction away from the switch element.
Is biased by the biasing member. The operating member that is biased in this way is automatically moved in a direction away from the switch element after being once depressed, so that erroneous operation of the switch element can be restricted.

Further, the operating member is supported so as to be able to move forward and backward with respect to the switch element and is rotatably supported, and an operating section for operating the other switch element is provided. An operation is performed.

When a is directly pressed, a can be made sufficiently longer than the pressing stroke. Therefore, it is possible to reliably recognize the operation state of the small second switch element 6 in which the movement stroke of the operation element 6a is small and it is difficult to determine the operation state of the operation element 6a.

By the way, when a load greater than the urging force of the spring member is applied to the operating element 6a, the operating element 6a comes into contact with the contact, and the second switching element 6 switches the switch. Done. At this time,
Assuming that the load when α is pressed against the urging force of the spring member and brought into contact with the contact is α (N), the coil spring 4 interposed between the pressing operation member 25 and the operation element 6a
The spring constant K (N / mm) of 3 and the compression stroke t (m
m) has the relationship α (N) = K (N / mm) × t (mm).

That is, the pressing operation member 25 presses the coil spring 43 so as to compress it, and K (N / mm) × t (m
When the value of m) exceeds the value of α (N), the operating element 6a is pressed against the urging force of the spring member and contacts the contact.

Therefore, when the second switch element 6 is switched, the moving stroke of the pressing operation member 25 can be changed by appropriately changing the coil spring 43 to be used. Can be set. That is, the spring constant K (N / m
When the coil spring 43 having a small value of m) is used, it is necessary to increase the compression stroke t (mm).
When the moving stroke of the pressing operation member 25 is increased and the coil spring 43 having a large spring constant K (N / mm) is used, the compression stroke t (mm) needs to be reduced. The movement stroke of the member 25 is reduced.

As described above, by appropriately selecting the spring constant K (N / mm) and the compression stroke t (mm) of the coil spring 43 interposed between the second switch element 6 and the pressing operation member 25, the same value is obtained. It is possible to arbitrarily set the movement stroke and the pressing operation feeling of the pressing operation member 25 that switches the switching elements while using the pressing operation type switching element.

Here, the pressing element 40 is interposed to press the coil spring 43 against the operating element 6a.
The operating element 43 may be directly pressed by the coil spring 43 without using 0.
