Acer 6511-TW

[Shouner]

Hello everyone,

I just found this keyboard in my basement. Is this keyboard a mechanical one? If yes what is the switches use for it.

Thank you for helping me.

A quick search reveals the answer: rubberdome.

Spring over membrane, or rubber dome over membrane, or—like with Peerless—both?

And what makes it click — the implication seems to be that it will be something like Peerless (and I don't know why that clicks, despite having completely stripped and reassembled one).

Spring over membrane

So it's like a cut-down version of the more common Acer switch?

The photo from didjamatic appears to depicts a slider over rubber dome.

It appears that 631x and 651x were parallel series, as I've found examples of both each in both the "angular" and "curved" style cases.

HaaTa's old-style 6511 with the same sliders as didjmatic's: http://geekhack.org/index.php?topic=12244.0
A 6512 with 631x-style backplate and additional keys: http://www.digicoll.com/tecladosyratones.html

Most (-TA and -VA) have three extra keys in the navigation cluster, but there are both angular and curved style ones that don't.

I'm guessing that depending on how much you paid, you could get rubber dome over membrane (651x) or "mechanical" over membrane (631x).

Also, Acer even used that sleek angular case (and I do love Acer's angular cases) for the 6011 mechanical:
