Abstract

A rotary switch device includes a terminal base to which a center portion contact and a fixed contact member are fixed, a movable contact member, and a support portion. The movable contact member includes a contact protrusion part which is pressed in contact with the center portion contact at one end of the movable contact member and a first contact surface which is in contact with the fixed contact member at another end of the movable contact member, and which is operated to rotate around the center portion contact so as to short-circuit between the center portion contact and the fixed contact member at a conductive rotation position.

First claim

What is claimed is:

1. A rotary switch device comprising:
a terminal base to which a center portion contact and a fixed contact member are fixed;
a movable contact member; and
a support portion,
wherein the movable contact member includes a contact protrusion part which is pressed in contact with the center portion contact at one end of the movable contact member and a first contact surface which is in contact with the fixed contact member at another end of the movable contact member, and which is operated to rotate around the center portion contact so as to short-circuit between the center portion contact and the fixed contact member at a conductive rotation position,
wherein the support portion is formed in the terminal base and supports an edge corner portion along a rotation direction when the first contact surface of the movable contact member is operated to rotate, and
wherein the moveable contact member is configured to slide on the support portion with the edge corner portion as a sliding contact portion and moves to the conductive rotation position in which the first contact surface is in contact with the fixed contact member.

2. The rotary switch device according to claim 1 ,
wherein the support portion supports the movable contact member at a high position with respect to a plane of the fixed contact member, and in a supporting state, holds the movable contact member in a state that the movable contact member is rotatable in a direction perpendicular to the plane.

3. The rotary switch device according to claim 1 ,
wherein the first contact surface of the movable contact member and a second contact surface of the fixed contact member are formed in rectangular shapes in which a contact portion of the first contact surface of the movable contact member with the second contact surface of the fixed contact member moves from one end portion of the movable contact member to another end portion of the movable contact member in a predetermined connecting operation angle from a start of a contact between the fixed contact member and the movable contact member, and the movable contact member uses the corner portion on a contact end point side as the sliding contact portion with the support portion.

4. The rotary switch device according to claim 3 ,
wherein conductive processing for corrosion resistance is applied to the first contact surface of the movable contact member and the second contact surface of the fixed contact member.

5. The rotary switch device according to claim 1 , further comprising:
a plurality of movable contact members that moves on a same circular moving locus.
