20080237015 | CATCHMENT MECHANISM TO PREVENT CAMSHAFT OVER-ROTATION DURING CLOSURE IN A DIRECT-DRIVE STORED ENERGY MECHANISM - A catchment mechanism for an electrical switching apparatus operating mechanism is provided. The catchment mechanism includes a catchment wheel with a radially extending surface, a catchment prop, and a catchment prop reset pin. The catchment wheel rotates with the cam in the closing assembly as the closing springs are being charged. During the charging of the springs, the catchment prop stop edge travels over, but preferably does not engage, the wheel outer surface. When the closing springs are released, the catchment prop stop edge engages the catchment wheel radially extending surface thus causing the catchment wheel to stop rotating. As the catchment wheel is fixed to the cam shaft, the rotation of the cam shaft, and therefore the cam, is also stopped. The catchment wheel radially extending surface is positioned so that the cam is stopped in an appropriate position to begin recharging the closing spring. | 10-02-2008 |

The sensing switch coupled to, and in electronic communication with, the control unit. The sensing switch is disposed adjacent to the toggle assembly. The sensing switch is structured to provide a sensing switch signal to the control unit. The sensing switch actuator is disposed on the toggle assembly. The sensing switch actuator is structured to actuate the sensing switch. The sensing switch is structured to be actuated by the sensing switch actuator when the toggle assembly is in the second, over-toggle configuration. | 12-11-2008 |
