oh.. I am trying to make a type of rail that goes underneath a photo transistor and trigger this photo transistor to turn on/off a motor. I will have the motor on as long as the photo transistor is passing over the ir sensors. It's kind of long...
What is the distance between the TX'ing and RX'ing parts?
Have you considered a reed switch and 2 magnets (+ an extra magnet to make the reed switch bistable)?
What about plain old microswitches?
A LASER pointer and 2 skewed mirrors?
