<p>Disclosed is a switch device operating mechanism provided with: a closing spring (16) which rotates a camshaft (3) with freed energy to provide a closing drive force for closing the contact of the switch device; a first crescent latch (5) which holds the stored energy of the closing spring (16) by means of a closing lever (6); an output lever (10) which, when the energy of the closing spring (16) is released by releasing the holding by the first crescent latch (5), applies pressure to and rotates a cam (2) disposed on the camshaft (3), and transmits the closing drive force to the switch device via a linking mechanism; and a second crescent latch (13) which prevents by means of a trip lever (8) that the output lever (10), to which is transmitted energy freed from an interrupt spring disposed in the linking mechanism, rotate in the trip direction, and which holds the stored energy of the interrupt spring.</p> |
