Abstract
A suspended pull or control switch is provided for overhead mechanical devices, such as power hoists, in which the control switch is so suspended and configured to be physiologically oriented with respect to the attendant's position that the attendant may grasp and visually consult the switch over a long period of time without becoming as fatigued as is the case with conventionally positioned switches. This is achieved by configuring the body of the switch, or at least that portion grasped, to be angled from the vertical axis of suspension of the switch to that degree necessary for the handle portion to be ergonomically work-oriented with the attendant's hand and angle of vision. A dual control switch may be utilized in which both hands of the attendant would be conformed to.
