Plus you'd need two switches for the two positions meaning you'll also need a smart relay to understand the two switches and control the system accordingly. It's certainly not as simple as described and the cost would be beyond $39.

Monsieur MitchM wants 2 directions only, which means he needs one sensor and 2 magnets 180 degrees apart, the timer falls off, the motor turns, the sensor sees the magnet and the timer turns on again, he can drop a small cam onto the upper mag unit if he wishes and install a micro switch in the underside of the motor mount, there are many ways to do it.

BTW that still wouldn't work as simply as you think. Once the switch makes contact and shuts off the movement what then tells it to move on? You still need a smart relay. And you can't run a cam, is it not sealed to prevent water leakage, it would think it would have to be magnetism which wouldn't react properly with the magnets already present.

Oh shoot didn't realize we were in a vendor forum. Not sure my links are appropriate here. Also forgot golfnut = paul lol.

It is running on my desk as we speak

I am sensing the motor shaft which is directly related to the magnets on the other side of the membrane.

So how does it work with a smart relay?? I think you'll have to post a video.

I will try to get some time and capture it, it works with the $39 parts I posted earlier.

Describe works. I mean does it work by itself or do you have to put input into to it. I'm curious how the system will work without some kind algorithm, once the switch is triggered and it turns off the motor how exactly is this reset so it can continue until it hits the next switch?

It's a count down timer, when the motor turns and a magnet effects the sensor the power triggers the timer to start counting down and turn the motor off, once time down has occurred power goes to the motor, it turns and when the next magnet is seen it repeats, you can time down anywhere from seconds to weeks depending on the timer used.
