May I ask what keyboard you are using?
Please be careful that the contact leaf (the one with the thinner pin, the one that touches the stem) is fully inserted into the switch housing before you solder the switches. The Outemu tops don’t have the 2 little “teeth” that the Aliaz tops have that hold the leaf down keeping it in position. Shouldn’t matter once the pins are soldered in.
If you are using hot swap, I would consider a different top, because I made this recipe with the Outemu tops and used it in a hot swap board, and some of the switch leaves rode up out of their proper position over time, causing the switches to chatter. I changed to Greetech tops later to solve that problem.
Here is a compatibility matrix for different bottoms and tops and what issues you could run into:
