PROBLEM TO BE SOLVED: To provide a switch apparatus having an opposite slide contact mechanism in which a contact gap with a fixed contact at the time of a neutral point is sufficiently ensured without lowering a contact pressure against the fixed contact of a movable contact during a full stroke. SOLUTION: An always closed contact 21 is shaped having an inclination such that a movable contact 16 is slid and moved, and becomes higher as it approaches to a full stroke. When the movable contact 16 is in a neutral state, the movable contact 16 comes into contact with a flat face 21a of the always closed contact 21, and a sufficient contact gap quantity can be ensured. In addition, when the movable contact 16 is at a full stroke position, the movable contact 16 comes into contact with a inclined face 21b of the always closed contact 21, an extension quantity A' of a plate spring in the neutral state and at the full stroke position is reduced, and the contact pressure can be ensured. |
