The outer housing provides the adjustment and the lockdown. Check yours for cracks around the brass insert. This is what holds the switch adjustment in place after setting the stops on the car.

Putting the switch back together is the hardest part. It's a two person job without special fixtures. By folding tape on itself so there is no sticky against the rollers. This setup will allow you to insert the carrier into the housing without the parts popping out. Note the position of the spring and the orientation of the carrier of the bottom half of the switch.

You can see the first carrier installed. Peel the sides of the tape away and pull on the tab to remove the tape. You will have to gently pivot the carrier away from the tape without letting the rollers out.

Use a small hook tool while a helper inserts the second carrier. This pre-loads the spring and holds to two carriers in position. The center pivot is what actually changes the contact positions at the extreme ends. Hold it together with your fingers until you get the tape out and the cover back on. Once back together, you can adjust it on the car.
