I know it's a stretch but i'm wondering if I cant get some help figuring out what kind of switches my keyboard has. I'm looking to buy a new keyboard and i'd like the feel of the keypress and the sound to remain as similar as possible, but I cannot find any specs on my keyboard because i'm pretty sure it's discontinued.

I've looked at the differences between switch types but it's a little hard to figure out which is similar to mine when this is pretty much the only keyboard i've ever used so i dont have a feel for comparison. Is there an easy way to figure out what kind of switches it has? like taking a key off and it being a certain color underneath? Forgive my retardation, I'm lost and confused.

-I took a keycap off and there doesnt seem to be any kind of switch or spring or anything. Deep inside the square hole that the keycap sticks on there seems to be a little white rubbery circle. Any idea what that is?
