Hello,

I'm assuming your resistance question ask about the spring rate/caracteristics of the switch (sorry if this is not the case).

I can tell you only that I used the closest available switch from the original I could find at the time. I can't tell you much about other options available since I didn't try any other.

I can point you to this article : https://geekhack.org/index.php?topic=817..., which might provides you with the info about the "specs" you're looking for in a replacement switch.

it’s all philips screws, i used a size 0
