Patent ID: 8664556

Claim:
A switch device operating mechanism comprising: a closing spring which provides a closing drive force for closing a contact of a switch device by rotating a camshaft by release of energy; a first semi-circular latch which retains stored energy of said closing spring via a closing lever, the stored energy being transmitted from said camshaft; an output lever which pivots by being pressed by a cam provided on said camshaft when retention by said first semi-circular latch is released and the energy of said closing spring is released, and transmits the closing drive force to said switch device via a linking mechanism; a second semi-circular latch which prevents said output lever from pivoting in a tripping direction via a tripping lever and retains stored energy of an interrupting spring provided on said linking mechanism, the pivoting of said output lever being caused by transmission of the stored energy of said interrupting spring; wherein said closing lever is formed with a latching section at one end side and the other end side is pivotally supported, and a pin is provided at a position near a pivot center section between the latching section and the pivot center section; and said pin is pushed by rotation of said cam to pivot said closing lever, and the latching section of said closing lever is engaged with a cutout section formed on said first semi-circular latch, whereby, the stored energy of said closing spring is retained.
