Description

The present invention relates to a pressing operation type multi-stage switch device.

In Patent Document 1, a pressing operation type two-stage switch device is proposed.
In this press operation type two-stage switch device, a second switch is provided above the first switch, a first input member and a first spring (coil spring) are disposed above the first switch, and the second switch is disposed above the second switch. When the second input member is arranged, the second spring (coil spring) is arranged between the first switch and the second switch, and the operation button connected to the first input member and the second input member is pressed, The first input member inputs the first switch by the first pressing force, and the second input member inputs the second switch by the second pressing force continuously applied from the state where the first pressing force is applied. .

JP 2007-188797 A

However, in the press operation type two-stage switch device disclosed in Patent Document 1, the first input member and the first spring (coil spring) are arranged above the first switch, and the second switch provided on the upper layer of the first switch. Due to the structure in which the second input member is arranged, there is a problem that the mounting height of the switch is increased.
And since there exists a 2nd spring (coil spring) between the 1st input member of the upper side of the 1st spring (coil spring) and the 2nd input member of the upper side, there also exists a problem that adjustment of the stroke load of a button is difficult. .
Furthermore, if the operation button is pressed and then the first switch is input and then the second switch is input, the operation button cannot be pushed any further. For example, when applied to a camera shutter switch, from half shutter switch input to shutter switch input. There is a problem that the shutter button is not pressed well and camera shake is likely to occur.

The subject of this invention is making it easy to adjust the stroke load of an operation button, reducing the mounting height of a press operation type two step switch apparatus.
Furthermore, another object of the present invention is to improve the feeling of button operation by allowing the operation button to be pushed further even if the second switch is input after the first switch is input.

In order to solve the above problems, the present invention provides:
A substrate having a first fixed contact and a second fixed contact on the same plane;
A first movable member having a first movable contact that can contact the first fixed contact;
A second movable member having a second movable contact capable of contacting the second fixed contact ;
A first coil spring that urges the first movable member in a direction in which the first movable contact contacts the first fixed contact;
A second coil spring that urges the second movable member in a direction in which the second movable contact comes into contact with the second fixed contact ;
Disposing the second coil spring on a concentric circle on the inner peripheral side or the outer peripheral side of the first coil spring;
With the first movable contact in contact with the first fixed contact and the second movable contact in contact with the second fixed contact, a pressing operation is input to the first movable member from a hole formed in the substrate. Then, after the first movable member moves against the urging force of the first coil spring and the first movable contact is separated from the first fixed contact, the first movable member is moved to the second movable member. The second movable member moves against the urging force of the second coil spring, and the second movable contact is separated from the second fixed contact .

According to the present invention, it is possible to lower the mounting height of the pressed-type multi-stage switch device, the stroke load operation buttons Ru can be easily adjusted.
