CLUTCH ASSEMBLY FOR ELECTRICAL SWITCHING APPARATUS WITH LARGE COMPRESSION CLOSE SPRING.

摘要

A clutch assembly for an electrical switching apparatus (1) which has a close spring (18) working in conjunction with a cam (107) disposed on a cam shaft (115), wherein the close spring (18) provides a rotational force to the cam shaft (115) in a forward direction. The spring clutch assembly (220) is disposed on the cam shaft (115) and allows the cam shaft (115) to rotate in the forward direction but prevents rotation of the cam shaft (115) in the opposite direction.
