Eaton Cutler Hammer Rotating Shaft Switches

	Rotating Shaft Switches — Type J

Rotating Shaft Limit Switches allow the shaft to be rotated a preset number of revolutions (adjustable from 1/2 to 100 with an accuracy of 1/20 of a turn) before the contacts will switch. A second set of contacts will trip when reaching a pre-set limit in the opposite direction. These switches are typically used in crane and hoist applications to provide end of travel stops for the hook assembly.
