Claims

[Scope of utility model registration request]

A fixed contact spring is made of an elastic plate material with high rigidity, the proximal end is fixed, and a fixed contact is provided near the distal end, and a fixed contact spring is made of an elastic plate material with lower rigidity than the fixed contact spring, the proximal end is fixed and the fixed contact is connected near the distal end. In a contact opening/closing device comprising a movable contact spring provided with a movable contact to be separated, and a drive means for driving the movable contact spring to cause both the contacts to move toward and away from each other, a tip of the fixed contact spring is provided with a movable contact spring on the movable contact spring side. The movable contact spring has a bending portion that is bent, and the movable contact spring has a large moment of inertia in the area where the movable contact is provided and is driven by the driving means, and the movable contact spring has a distal side portion and a proximal side portion with respect to the portion where the movable contact is provided and is driven by the driving means. 1. A contact opening/closing device characterized in that the tip side portion contacts a bent portion before both contacts come into contact during a contact contact operation.
