The indicator is especially useful for an industrial truck with a steerable wheel which can be turned through a steering arc of as much as one hundred eighty degrees. The indicator includes a potentiometer mechanically coupled to be rotated in synchronism with the steering rotation of the steerable wheel, and a multiple voltage threshold detector circuit connected to receive the variable voltage from the potentiometer and operable to provide one out of N discrete output signals in response to potentiometer voltages which have predetermined voltage level relationships to the respective voltage thresholds. At least N discrete indicator lamps are arranged in an array for indicating steerable wheel direction, and the indicator lamps are connected to receive the discrete output signals from the multiple voltage threshold detection circuit for indicating travel direction.
A wheel direction indicator for a steerable wheel which is especially useful for a vehicle such as an industrial truck of the kind which has a steerable wheel which can be turned through a steering arc of as much as one hundred eighty degrees, said direction indicator comprising a mechanical motion to voltage transducer mechanically coupled to be rotated in synchronism with the steering rotation of said steerable wheel, a multiple voltage threshold detector circuit connected to receive the variable voltage from said transducer and operable to provide one out of N discrete output signals on one out of N discrete output connections respectively in response to transducer voltages which have predetermined voltage level relationships to the respective voltage thresholds, at least N discrete indicator lamps arranged in an array for indicating steerable wheel direction, said indicator lamps being connected to receive said discrete output signals from said multiple voltage threshold detection circuit for indicating travel direction.
