Modding Topre switches? (lightening it)
« on: Sun, 18 March 2012, 23:34:22 »
Posted a few posts about the stiffness on my HHKB (55-60g on my 37 keys), used it pretty intensively for a week and its still too stiff for my heavy usage. Also realized its probably not going to become lighter magically by itself. So, before selling it (and perhaps buying another one after), I would like to make one last attempt to get it to work for me. (because I really adore the layout and the feeling of the switches, bar the heavyness)

Are there any ways to reduce the actuation weight of the keys, perhaps by some simple modding? Switching the rubber around probably won't work though, most of the 37 keys seem pretty much about the same weight. Is it possible to buy these rubbers? (probs not i guess). (Removing the spring gives me 5g, but I doubt the switch would work lol :P)

Also, if anyone wants a HHKB (white/grey blank) with slightly heavier switches and have an existing one to trade,  we may be able to come to an agreement for a trade.

Simplest way is to replace its rubber sheet with 30g  one.
Secondly you can make hole on rubber cup with hole punch.
Or you can get it some lighter by shorter stroke from  side effect of silence mod.

Did you try to get warranty replacement? Since you bought them only a week or two ago, if you bought the board from a dealer, I guess they will be sympathetic. I think it would be worth a try. Moreover, I heard somewhere Topre replaces rubber sheets if it is defective. But I don't know whether they have foreigner friendly policy though.. If you could convince them they may send you a replacement rubber sheets. (This is my speculation. I do not have any information how Topre's warranty works.)

Omg, if i can find the rubber sheet for 30g, it'll be freaking awesome but is it possible to buy that separately at all?

I'll pass on the hole punch just in case I need to sell this set lol.

Ill check out the silence mod (your sig:D)

Mmm, the weight still seems to fit into the +/-15g range which isn't good for me..Also, the warranty card in the package says warranty only valid in japan and I'm not sure if Amazon JP offers international RMA though. (it only ships within JP)


EDIT: Does anyone know how Amazon treats "defective" goods? If the keys are overly stiff, is it considered defective? Their pages seem to suggest that unless its defective, any opened goods will only get me 50% refund heh.

This page says Amazon.co.jp exchanges it or refunds 100% if your goods is defective.

Yeah, mostly I was afraid they might not regard this as defective (it being within the limits of +/-15g). Oh well. I have less than a week to make a decision about this before its not eligible anymore lol

Limit of +/- 15g doesn't make sense at all if they are selling 55g as a different board from 45g. Wouldn't it be strange if 60g is normal actuation force for 45g, and at the same time they are selling 55g board? I could accept +/- 5g deviations out of factory, but 15g deviation is just too much inaccuracy. Were did that 15g deviation come from anyways?

Document your findings by taking pictures and argue it well. I personally think your board is defective if it actuates at 60g.


Edit: I see that +/- 15g here. http://www.topre.co.jp/e/products/comp/key_point.html
However, if every switches are +15g from the original specification, then it certainly seems defective to me.
