Abstract

An inhibiter switch is configured to include a fixed contact point that is connected to and disconnected from a movable contact point. The movable contact point is configured to make pressure contact with the fixed contact point by the movement of a movable board by a shaft member, wherein a press-fit amount of the shaft member to a projecting portion is made smaller toward a connecting portion between the projecting portion and an inner periphery of an insert hole of the movable board.

First claim

What is claimed is:

1. A switch comprising: a movable contact point;
a movable board provided with the movable contact point;
a shaft member that moves the movable board, the shaft member being jointed to the movable board by being press-fitted in a projecting portion projecting from an inner periphery of an insert hole in the movable board; and
a fixed contact point that is connected to/disconnected from the movable contact point by causing the movable contact point making pressure contact with the fixed contact point to move by the movement of the movable board by the shaft member, wherein a press-fit amount of the shaft member to the projecting portion is made smaller toward a connecting portion between the projecting portion and the inner periphery of the insert hole;
wherein an inclined surface is formed in the projecting portion in such a direction that a press-fit amount of the planar portion to the projecting portion is made smaller toward the connecting portion as viewed from the axial direction.

2. The switch according to claim 1 , wherein
a planar portion configured as a linear outer periphery as viewed from an axial direction of the shaft member is formed
in a joint portion to the projecting portion in the shaft member, the shaft member is jointed to the movable board by press-fitting the planar portion into the projecting portion.

3. The switch according to claim 2 , wherein
the planar portion configured as the linear outer surface formed in the joint portion includes a pair of planar portions
provided to be symmetrical across a center shaft of the shaft member as viewed from the axial direction.

4. The switch according to claim 1 , wherein
the movable board is provided to be movable around a center shaft of the shaft member, and the movable contact point
making pressure contact with the fixed contact point is moved in a circumferential direction around the center shaft with rotation of the shaft member, thus connecting/disconnecting the movable contact point and the fixed contact point.

5. The switch according to claim 2 , wherein
the movable board is provided to be movable around a center shaft of the shaft member, and the movable contact point
making pressure contact with the fixed contact point is moved in a circumferential direction around the center shaft with rotation of the shaft member, thus connecting/disconnecting the movable contact point and the fixed contact point.

6. The switch according to claim 3 , wherein
the movable board is provided to be movable around the center shaft of the shaft member, and the movable contact point
making pressure contact with the fixed contact point is moved in a circumferential direction around the center shaft with rotation of the shaft member, thus connecting/disconnecting the movable contact point and the fixed contact point.

7. The switch according to claim 1 , wherein the shaft member is press-fitted along an outer peripheral edge of the shaft member.

8. The switch according to claim 1 , wherein the press-fit amount of the shaft member to the projecting portion is made smaller linearly.
