[K3] question to Elecraft staff /Wayne about K3 keytop mfg...

[Bill Wiese]

Hi, Wayne & crew...

I'm quite interested in the nature of your labelled keytops/keypads - are these all part of one
giant molded 'pad', or are they separate 'button by button' entities?  Are these soft rubber, or
are they hard?  I seem to recall a comment a week or so ago that something was done to stop these
K3 keytop legends from wearing off (unlike those, say on a Kenwood 570 :) )

If you'd care to publicly or privately - my email addy is below - share some vendor info and/or
some broad ballpark costs on NRE & unit pricing and initial volumes, it'd be really helpful to me
for a possible non-competing, non-ham-radio/nonradio smaller-volume project.  I just need to know
some relative order-of magnitude info and nothing that would give anyone any proprietary edge on
you.  There's little info Googleable, etc on this as so much mfg involving keytops is large scale
stuff in Far East (10 million remote controls or calculators or microwave oven keys, etc.)

I can be reached via this list or at 'wmwiesejr[_at_]yahoo[*dot*]com'

And yes, I will be tempted by a K3 later this year after a few other priorities are taken care of.


Regards, Bill

Anyone got a FT-857D or FT-897D they want to trade for a K2.  The K2 has
KSB2, K160RX, KNB2, KAF2, and KAT2 in it, also the MH-2 Mic.

Michael,

I believe this is the data you are looking for.

"The K3's front panel switches do provide positive tactile feedback, via
integral polydomes. The material we selected is rated for extended
lifetime (many decades, in this application), and the silver contacts
are fully sealed. As for the printed legends, they're protected by a
matte silicone hardcoat that's impossible to rub off.

In addition to the tactile feedback, we provide visual and audible
confirmation of every switch closure.

Hi Bill,

Two large arrays -- one on the left side, one on the right. This
ensures accurate registration.


> Are these soft rubber, or are they hard?

We tried several durometers and settled on one that is "medium"
hardness. You'll like the feel  :)

They don't rub off.
