摘要： A handle of the type adapted to prevent overloading of a mechanism with which it is operably associated, wherein a significant length of the handle is designed such that all points lengthwise thereof will simultaneously experience the same bending stress when a mechanism-operating load is applied to the handle, thereby resulting in a noticeably bending deformation of the length of handle before failure of the handle.

摘要： The hoist control features a casing of pistol grip like construction, which serves to enclose electrical switches, and an externally mounted rocker operator for controlling operation of the switches. Rocker movement is transmitted to the switches through a moisture sealing diaphragm and a switch actuating means arranged within the casing for movement in response to rocker induced movement of the diaphragm.
