I've a coil winder and need to control a DC motor that drives a carriage back and forth, left to right, this feeds the wire onto the bobbin. Previously this was driven by a stepper motor via a H bridge with PC software, I'm now trying to do the same but with switches, but can't figure out how to do this without using 4PDT push latching sw's but that's no good as the sw shaft is in a different position by about 1/4" in each "state"

How can I do this simply either with transistors or simple sw's or both? One sw will be fixed, the other moveable according to how wide the bobbin is.

Andy.
