Patent ID: 7538283

Claim:
A switch device, comprising: a switch base plate that includes a sliding surface on one side thereof, and has conducting patterns of a predetermined shape provided on the sliding surface; a sliding member that is provided with a first claw portion and a second claw portion, the sliding member being latched at one end portion and the other end portion in a width direction of the switch base plate by the first claw portion and the second claw portion, respectively, and the sliding member also being supported by the switch base plate so as to be slidable in a sliding direction that is orthogonal to the width direction of the switch base plate; a contact member that is formed from a flexible conductive material and is disposed in a position opposing a sliding surface of the sliding member, the contact member being deformed by bending by a pressing force from the sliding surface in a state in which the switch base plate is latched by the first claw portion and the second claw portion, and the contact member is pressed against the sliding surface by a restorative force from the bending deformation; an extended portion that is formed at a leading end portion of the switch base plate, where one end side in a width direction of the leading end portion of the switch base plate is caused to partially extend further in the sliding direction than the other end side in the width direction, the extended portion also configured to be latched by the first claw portion; and a cut-out portion that is formed at the leading end portion of the switch base plate and causes the leading end portion of the switch base plate to be in a state of non contact with the second claw portion when the extended portion is in a state of being latched by the first claw portion.
