Claims

[Claims for Utility Model Registration] 1. By performing a closing/unloading operation via a toggle mechanism that selectively rotates the drive shaft in either the closing direction or the opening direction, the force of the opening spring is stored at the time of closing. In a switch that quickly cuts the opening/closing part by the biasing force of the opening spring when opening, a force is stored on the drive shaft when the drive shaft is opened, and when the drive shaft is closed, the stored force is used to close the drive shaft. 1. An opening/closing operation mechanism for a switch, characterized in that a biasing mechanism is arranged in conjunction with a biasing mechanism that biases the switch in the closing rotation direction. 2. The toggle mechanism has a toggle lever fixed to an operating shaft, one end of which is rotatably attached to the shaft, and the other end of which is slidable relative to both ends of the toggle lever that are located 180 degrees opposite each other. A pair of spring support plates to be attached, and a pair of spring support plates attached to each spring support plate,
When the attachment point of the spring support plate to the toggle lever crosses the dead point connecting the rotation axis attachment point of the spring support plate and the operation shaft, the toggle lever can be selectively rotated in either the closing direction or the opening direction. The opening/closing operation mechanism for a switch according to claim 1, which is constituted by a coil spring attached to a coil spring. 3. The biasing mechanism has one end rotatably pivoted,
A practical device consisting of a spring support member whose other end is connected to the toggle lever, and a coil spring which is attached to the spring support member and whose one end biases the operating shaft in the closing direction via the toggle lever. An opening/closing operation mechanism for a switch according to claim 1 or 2 of the patent registration claim.
