While not an inexpensive part, it was much less expensive than replacing the opener. Also less time consuming and easier. An overall good purchase.

I was trying to fix my brother-in-law's garage door opener and saw that the metal contacts on the limit switch were broken so I ordered the first on I saw, which was wrong. He has a screw-type opener, not sure if that matters, but the "Liftmaster 41D4671 Screw Drive Limit Switch" looks like the correct part. REGARDLESS, these things are practically identical and what you likely really need is the metal contacts... DON'T TRY TO REMOVE THE METAL CONTACTS.Everything on this switch is very simply designed, if you ordered the wrong part, check out my ugly diagram for information regarding how to use parts from your bad switch. The difference between these two switches is the gear on the end of the center shaft; you can't simply remove that gear from the 'wrong' part, but you can simply pop the shaft assembly loose. Chances are, you also need the metal contact piece as well, don't try to remove that metal from its plastic housing, just unscrew it from the shaft and then screw it back on to the old shaft and pop it back into place.Lemme tell you why these break! The blade connectors that fit onto this switch are VERY LOOSE! They fall off and your first instinct is to try to tweak those screws on the side of your opener; now you've tweaked the screws too much and the metal contacts on the center shaft have snapped off. Use pliers to crimp down on the blade connector so that it actually sits tight on the switch and doesn't fall off, also watch how the switch travels and consider not running the wire through the plastic loops on the upper-left and lower-right of the unit or else the wire may get pulled loose (again!).
