Patent ID: 7755460

Claim:
A micro-switching device comprising: a fixing member; a movable part including a first surface, a second surface opposite to the first surface, and a stationary end fixed to the fixing member; a movable contact electrode including a first contact portion and a second contact portion formed on the first surface of the movable part, both the first contact portion and the second contact portion being spaced apart from the stationary end in a predetermined offset direction, the first contact portion and the second contact portion being spaced apart from each other in a direction intersecting the offset direction; a first stationary contact electrode bonded to the fixing member and including a third contact portion facing the first contact portion of the movable contact electrode; a second stationary contact electrode bonded to the fixing member and including a fourth contact portion facing the second contact portion of the movable contact electrode; and a drive mechanism including a driving force generation region on the first surface of the movable part; wherein a distance between the first contact portion and the third contact portion is smaller than a distance between the second contact portion and the fourth contact portion, the driving force generation region having a center of gravity closer to the second contact portion than to the first contact portion.
