2. Étape 2 Remove the back lid
  Use a small flat-headed screwdriver, spudger, or similar to pry open the lid enough to be able to get a grip of it and pull straight back and then fold down.
  
  The back of the lid has a PCB with cables connecting it to the motherboard inside the unit. While not particularly fragile, do take care so you do not damage the connectors.

4. Étape 3 Unplug the cable for the limit switch
  In my case the replacement limit switch was delivered already connected to a cable. If you are only replacing the actual switch you can skip this step and instead unplug the opposing end on the switch itself later..
  
  Remove the limit switch cable connector in the bottom right corner by pulling it straight out.
  
  Be sure to pull the connector, and not the cables!

I've looked everywhere and can't seem to find a place to buy a replacement limit switch. Any suggestions?

I got my replacement directly from Elegoo support. Send them an email, they are very helpful.
