A method of manufacturing a steering column stalk switch apparatus includes the steps of fixedly engaging a hub attached to an elongated shaft to one end of a hollow housing having apertures formed at opposite ends, movably mounting a button in one of the apertures in the housing, the button being movable between first and second positions and biased to the first position, mounting a first electrical contactor having first electrical contacts thereon in the button, movably mounting a second electrical contactor with second electrical contacts thereon in the housing, the first and second electrical contacts being co-planarly aligned, mounting a circuit board with conductive tracings in the housing such that the first and second contacts slidably engage the conductive tracings and complete circuits therebetween depending upon the position of the first and second electrical contacts, mounting the second electrical contactor on a movable carrier in the housing, biasingly mounting a detent paw on the carrier, aligning an arm mounted on the hub and having first and second spaced detents and an angular ramp extending from the second detent with the detent paw for selective engagement of the detent paw with the first and second detents and for movement along the annular ramp as the carrier undergoes user generated movement, and forming the conductive tracings at discrete timed intervals with respect to the position of the first and second electrical contacts.
