ABSTRACT:
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. An excitation circuit is provided for supplying a predetermined excitation signal to a receiving circuit which responsively produces a control signal. The control signal is modified in response to a predetermined movement of the control member. A control circuit actuates and deactuates the electrical device in response to receiving the control and modified control signals. Thus, the apparatus controllably actuates the electrical device while maintaining the control member electrically isolated from the power supply. The steering wheel is free to rotate without interconnecting wires or slip rings.
