I found while you can "usually" get the switches adjusted, the Mianne method of using standard momentary toggles with an angle bracket lends itself to easily getting "out of whack" and you have a real problem on the downward travel if the switch doesn't trip before the lift gate hits the stops. This makes the downward stop about as bulletproof as I can imagine using simple switches.
John, I've drooled over that spring loaded, idler pulley and micro switch you used. I couldn't find anything like that. I also take heed of your warning on adjustment issues. I'm hoping what I did with the spring on my hoist will simply keep some tension when the cable goes slack, certainly won't stop an unwind.
I've also noticed a good deal of noise from the cable. It appears loosely wound and will grab hairs on your head, so I think the noise is from it tightening under load. It sounds like grinding gears but I'm sure it's the cable.
