ABSTRACT:
An electrical transmission control mechanism includes a first printed circuit board having a first plurality of contact elements thereon, and a second printed circuit board connected thereto and having a second plurality of contact elements thereon. A transmission control assembly includes a control member movable laterally and adapted to cause travel of a holder and a first plurality of wiper members linearly across the first plurality of contact elements for selecting the direction of rotation of a transmission, and movable longitudinally and adapted to cause rotation of a second holder and a second plurality of wiper members across the second plurality of contact elements. A third printed circuit board is preferably mounted in parallel relation to the second printed circuit board and at a right angle to the first printed circuit board when a substantial number of gear ratios are used.
