last ditch effort to find a membrane keypad

hi:

it's true. only one in my catalogs - can't find the hosfelt cat, but
they're high $. i went to EEM and found some mfgs - even saw the keypad
from my tricorder (no kiddin' - trilithic SLM), but nothing like what
i'm looking for without a special order, i think.

i'm looking for something <= $15 encoder optional. the encoder would
have to be cheaper than 8 gen. purp. diodes. yeah, i optimise everything
but some of my posts :)

0-9, menu, up and dn arrows (optional- i can use menu to drill down),
enter, and maybe on/off and 2nd

16 keys 4x4 scanned matrix

tactile or non

1.5 - 2 sq.in.

i already found a 3x3" approx. and want a smaller one. the damn thing's
$16+ and $7 or so for the encoder. and the headers are xtra!

so before i go with switches, if anyone's seen a source for single
units, please give a shout.

and if anyone knows of a 16x2 to 20x2 character LCD w/HD44780 compat
controller under 3" wide, i'm interested. they all seem to be 3" wide.
fit my van inside 'em.

a case made to fit all that and mount a PCB would be the balls.

TIA,
mike

bgmicro SWT1067 ?
well, it's 1/2" too big each way, wrong keys, & too thick, but it's nice
to know about the company, anyway. they have a good price on LCDs. i
think they used to send me a catalog. i wonder how many times i drove
past that place on the way to breakfast at hubbard's kitchen where chuck
norris goes when he's in town.

so far, the smallest membrane keypad i've seen is from the remote
control that came with a soundblaster card.

tnx,
mike
