All you need are two limit switches. The instruction manual (linked at the bottom of the page on Amazon) shows how to attach two NPN proximity switches (https://www.amazon.com/Twidec-Induct...s%2C204&sr=8-7 and from the photo that you provided in post 12, I'd simply drill two holes in the side-wall an inch or so above the moving sled, one at each end of travel, and fit the proximity sensors there; Add a short piece of angle steel attached to the bolts on the linear blocks (you show 8 bolts in the image) to project up to provide a moving vane to actuate the proximity sensors when the sled is in the two end positions.

Job done.

can you please help
ive installed 3 of the uniquegoods 30 amp controllers with npn switches each end
all works 100% BUT i want to get rid of the remotes and use a simple push button hand controller
ive wired this into the manual switch but i can only get it to work by using only 2 of the 4 wires. i think im grounding the circuit so infact closing the switch. trouble as soon as i release the button the motor stops ( with remote it stays ngaged until it hits the npn switch. is there a quick fix to turn this bit into a stay on system so when release the BUTTON it keeps moving until it hits the end then it reverses the direction. As said it works NOW with the remote as one press keeps it moving. Do i need to wire the handpiece differently or use the 2 other wires in the manual bit. ( says that using the manual makes the remote redundant but it doesnt do this . Any help cheers Richard
