Abstract
A switch device includes: a movable spring that has one end as a fixed end, and the other end as a free end; a substrate that is disposed below the movable spring; a first contact point that is disposed at a predetermined location between the fixed end and the free end of the movable spring; a protrusion that is formed on the substrate and is located to face the free end of the movable spring; and a second contact point that is provided on the substrate and is located to face the first contact point. This switch device is put into an ON state when the free end of the movable spring is brought into contact with the protrusion and the first contact point is brought into contact with the second contact point.
Claims27
A switch device comprising:
- a movable spring that has one end as a fixed end, and the other end as a free end;
- a substrate that is disposed below the movable spring;
- a first contact point that is disposed at a predetermined location between the fixed end and the free end of the movable spring;
- a protrusion that is formed on the substrate and is located to face the free end of the movable spring;
- and
- a second contact point that is provided on the substrate and is located to face the first contact point,
- the switch device being put into an ON state when the free end of the movable spring is brought into contact with the protrusion and the first contact point is brought into contact with the second contact point.
A switch device comprising:
- a movable spring that has one end as a fixed end, and the other end as a free end;
- a substrate that is disposed below the movable spring;
- a first contact point that is disposed at a predetermined location between the fixed end and the free end of the movable spring;
- a protrusion that is formed at the free end of the movable spring;
- and
- a second contact point that is provided on the substrate and is located to face the first contact point,
- the switch device is put into an ON state when the protrusion is brought into contact with the substrate and the first contact point is brought into contact with the second contact point.
A switch device comprising:
- a movable spring that has an end as a fixed end;
- a substrate that is disposed below the movable spring;
- a first contact point that is provided to the movable spring except the region of the fixed end;
- a second contact point that is provided to the movable spring except the region of the fixed end;
- a third contact point that is provided onto the substrate and is located to face the first contact point;
- and
- a fourth contact point that is provided onto the substrate and is located to face the second contact point,
- the switch device being put into an ON state when the first contact point is brought into contact with the third contact point and the second contact point is brought into contact with the fourth contact point,
- the switch device being put into an OFF state when the first contact point is separated from the third contact point and the second contact point is separated from the fourth contact point.
A switch device comprising:
- a movable spring;
- a substrate that is disposed below the movable spring;
- a first contact point that is provided to the movable spring;
- a coil that is disposed on the substrate and is located to face a magnetic member;
- and
- a second contact point that is provided onto the substrate and is located to face the first contact point,
- the switch device being put into an ON state when the movable spring is attracted toward the substrate by voltage application to the coil and the first contact point is brought into contact with the second contact point by voltage application between the first contact point and the second contact point.
