Abstract
An operating element is provided between a hoist motor and the load therefor, which incorporates an integral handle. The handle includes a right-hand and a left-hand toggle switch connection so that the hoist motor can be operated with either hand. The handle is horizontal and connected at each end to the operating element by a web to provide an open space for insertion of the hand. The space is essentially surrounded to protect the hand from injury. The casing of the operating element is comprised of an upper and lower half made of a light-weight resilient synthetic material. The casing surrounds a yoke comprised of a heavy-duty material, which yoke provides a direct connection between the hoist motor and the load. Also, the yoke is configured to partially surround the main operating switch in the element for protection and includes opposed integral stops for limiting the extent of movement of the switch.
