Kailh brown vs Mx Brown

[Erzegovaz]

I usually use a fc660m with brown switch, but these days i`m trying a keyboard with kailh brown. I feel more weight and a little more bump...but i take a look at graphics and seems like the same.
Someone knows the exact difference?

Well, there are a few things that make switches different. The extra weight would be because of a heavier spring,and the bigger bump would be because of a slightly different stem
