Definitions
- the present invention relates to a push-type switch used for an electronic device, and more particularly, to a switch that is turned on and off when both ends of a built-in coil spring contact and separate from a contact terminal. Fine
- the “switch” of the prior art 1 is composed of “(Claim 1) a U-shaped case formed of a substantially square-shaped fixed terminal provided on the inner bottom surface and a conductive member having resilience.
- a contact piece of a torsion coil spring having a movable end having a contact portion bent in a substantially semicircular shape and a fixed end having a contact portion at a tip end substantially linearly, and a molded member.
- a switch comprising a cover for movably holding and holding the coil portion of the contact piece with the case.
- fixed terminals 112 and 113 are provided on the bottom surface of the case 111.
- the inside of the case 1 11 is made of a conductive material having spring properties, and one end of a coil spring 1 114 e is bent into a U-shape, and the end is further bent into a substantially semicircular shape.
- a movable end 1 1 4b having a contact point 1 1 4c is formed, and the other end is substantially linear and fixed to the end.
- a contact piece is formed to form a fixed end having a contact portion that makes contact with the terminal.
- the operating body 1 15 has a substantially bar-shaped U-shaped groove 1 15 a at one end, and the groove 1 15 a is extended over the movable end 1 14 c of the contact piece 1 14. Slide the contact in the direction to move the contact part 1 1 4 c and the fixed terminal 1 13 above.
- the cover 1 16 is a lid for enclosing the contact piece 1 14 in the upper part of the case 1 1 1.
- the cover 1 1 16 has a hole 1 1 6 a for slidably holding the operating body 1 1 5 and is further coupled with the case 1 1 1 to form a U-shaped recess 1 1 1 a of the case 1 1 1 And a protrusion 1 16b for holding the coil portion 114e of the contact piece 114 together.
- the prior art 1 formed in this manner moves the movable end 1 14 b downward by pressing the operating body 1 15 downward and sliding against the spring force of the contact piece 1 14. .
- the movable end 1 14 b moves the coil 1 14 e in the winding direction of the coil spring by moving the spring 1 1 4 e around the contact portion 1 1 4 d in contact with the contact terminal 1 1 2. It moves due to the spring force of the spring and the curvature of the movable end 1 1 4b.
- the contact portion 1 1 4 c is moved in the horizontal direction in Fig. 15 by moving the movable end 1 1 4 b downward, moves to the fixed terminal 1 13 position, and contacts the fixed terminal 1 1 3 Then, the fixed terminals 1 1 and 2 are brought into conduction with the fixed terminals 1 1 3.
- the contact piece 1 14 when the pressing of the operation body 1 15 ends, the contact piece 1 14 returns to its original position by its own spring force, and the contact section 1 14 c separates from the fixed terminal 1 13 and the fixed terminal. 1 1 2 and the fixed terminal 1 1 3 are insulated. However, in the switch of the prior art 1, the operating body 1 15 is slid downward and the fixed end 1 14 a and the movable end 1 1 '4 b of the contact piece 1 14 are fixed to the fixed terminal 1 1 2 and the fixed terminal.
- the operating force used to press the push switch is 0, and Ideally, the contact pressure between the contact piece and the fixed terminal is a set value, but in the conventional example, when the operating force for pressing the push switch is reduced, the contact pressure between the contact piece and the fixed terminal also decreases. Therefore, there was a problem that the operating force had to be increased to achieve the set contact pressure. In other words, when the operating force is reduced, the contact pressure is also reduced, and the contact pressure at the contact start position between the contact piece and the fixed terminal is different from the contact pressure at the time when the contact piece is further moved after the contact. There was a problem that the contact resistance at the contact start position was large, causing an error in the position determined to be conductive, and the accuracy of the detection position deteriorated.
- the present invention has been made in view of the above problems, and an object of the present invention is to provide a switch in which a change in contact pressure according to a position of a contact piece is small. Disclosure of the invention

- the contact piece provided in the case has a fixed contact portion at one end which is constantly connected to the fixed terminal, and a movable contact portion at the other end provided on the inner wall of the case by the elastic force in the torsion direction of the coil spring. It is pressed into contact with the inner wall of the case, and is positioned so as to be able to contact other fixed terminals. However, it is not contacted in the normal state.
- the contact piece is pushed by the operating body, and the movable contact portion is moved while being in contact with the inner wall of the case by the elastic force in the torsion direction of the coil spring, and comes into contact with another fixed terminal.
- the switch When the fixed contact portion and the movable contact portion of the contact piece come into contact with the fixed terminal, the switch short-circuits each of the fixed terminals to make them electrically conductive.
