Abstract
A handle is provided for an operator that provides overtorque protection for the operator. The handle includes a hand grip connected to a connecting shaft, which is mateably received in the operator. The connecting shaft includes at least one weakened section which breaks or fractures in the event an excessive amount of torque or force is applied to the handle. As a result, the handle breaks when the user applies an excessive amount of torque to the handle in an effort to open or close the structure connected to the operator. The broken handle may be easily replaced by removing the broken section of the connecting shaft from the operator and replacing the handle by inserting the new handle with a new connecting shaft into the operator. The gear mechanism disposed within the escutcheon of the operator is protected from the excessive amount of torque or force and, accordingly, the handle is intended to break before the operator which avoids the need for replacing the entire operator.
