1. A joy stick assembly, comprising a housing having top, bottom and side walls and an opening through said top wall; a joy stick extending through said opening, said joy stick having a resilient member around a medial portion thereof secured to said top wall in said opening and pivotally mounting said joy stick therein and on said housing in said opening for pivotal movement within said opening in any direction throughout a 360.degree. arc from an equilibrium position to an operative position and return and a member of electrically conductive material at a lowermost end thereof; and a plurality of contact elements of electrically conductive material on said housing bottom wall in an array in surrounding relationship to said conductive member, said conductive member being out of engagement with said contacts when said joy stick is in said equilibrium position and each said contact being engageable by said conductive member upon movement of said conductive member through an arcuate path as a function of pivotal movement of said joy stick away from said equilibrium position in a predetermined direction to electrically connect said conductive member and said contacts.
