-15- Abstract of the Disclosure Electrically Isolated Actuation Apparatus An apparatus for controllably actuating an electrical device in response to movement of a control member is useful, for example, in an industrial vehicle, including a chassis, a power supply electrically isolated from the chassis, and a steering assembly having a rotatably connected steering wheel. The subject apparatus includes a control member mounted on and rotatable with the steering wheel. Excitation means is provided for supplying a predetermined excitation signal to receiving means which responsively produce a control signal. Apparatus is also provided for modifying the control signal in response to a predetermined movement of the control member. Controllable apparatus actuate and deactuate the electrical device in response to receiving the control and modified control signals. Thus, the apparatus controllably actuates the electrical device while maintaining the modifying means electrically isolated from the power supply. The steering wheel is free to rotate without interconnecting wires or slip rings.
