not sure yet Kartman, something with say 4 - 8 keys that can be customised.  Not a keyboard.

There use to be lots of American companies doing them but I can't find anything apart from keyboards of the computer kind.

How many do you need?  I had custom membrane keypads made years ago and teh minimum was like 50 or so.  I can find teh Chinese vendor if you want.

Thanks jgmdesign. 

EDITED: yes, its a membrane keypad I'm looking.  Would be lovely to have some LEDs on it to.

I have attached a picture of a membrane keypad I had made. It has a row of bi-color leds at the top and three buttons at the bottom with a three inch tail coming from it.

Something like this?

To Jgm: Very nice keyboard.

but if you have low volume this technique is cheaper:

Is this commercial for real money? tooling might be $500 to $2500 , but then you can make a 20000 at 75 cents each.

 

Many many years ago, I worked a few weeks as a student job at a place that made touch phone keypads, that were essentially a sticker.  They used a conductive silver ink/paint that they kept saying ...don't spill that, this paint is $2500 a gallon!!

 

Talk about high volume...I think they made around a hundred thousand of these a day for Western Electric.  People were very impressed they could make a call without having to spin a dial.

Membrane keyboards are so "last century". In my experience most things I'm buying these days all seem to use touch controls. Might be worth a bit of research.

Digikey and Mouser both have product reps that can help you find resources like this!
Give them a call.

Maybe so.  But when I had those made the device was being used in an outdoor environment where readability/reliability is an issue(cracked screens in the desert are an issue), and we did not need all the fancy screen blah blah blah.  Hey, I got paid, customer is happy.  Move on in life right?

It's true it may depend on environment. 

 

I recently replaced our oven and hob with fancy new ones from Samsung. Both have touch controls. The oven looks like the flight deck of Concorde (or should I say an "A380" because Concorde was decidedly "analog"?) but on the whole it's touch controls work nicely. The induction hob on the other hand is another story. Because it's horizontal as soon as your potato water boils over and a bit of liquid gets anywhere near the touch controls they go "bonkers" and basically unusable until you wipe it clean with a cloth to remove any moisture. If the pan that boiled over did so because it's too high already then the panic that sets in because now the controls have gone unresponsive and you can't turn it down (and sometimes it just chooses to turn it up without any contact!) causes an interesting kind of panic.

 

So, yeah, touch controls, may not be the panacea for all ills!

Touch controls are a UI disaster in almost all scenarios - and I include mobile phones in that.

 

The biggest issue is lack of positional feedback, so you have to look at them to see where your poking.

Then variable sensitivity to environmental issues, as illustrated by Cliff.

Sensing fields which extend beyond the physical boundary of the switch - such as the edge of a mobile phone screen - and inhibit correct operation are another disaster.

As is lack of tactile feedback (yes I know about haptic efforts; they're not very good).

 

Oh, but I forgot - they're cheap. So that's all right then.

And sometimes that does NOT help.

 

There is, what I consider to be (and other internet posts seem to confirm) a design flaw in the Samsung controls. When turned on/lit up they look like this:

 

 

The one symbol in all that which is never lit is the on/off icon. So when this is "turned off" it looks more like:

 

 

At which point (in a fairly dark kitchen) this becomes a game of "hunt the invisible on/off button" !!

I put one of those sticky cabinet door bumpers on the light switch on our kitchen microwave (membrane) keypad.  Now it's tactile!

What sort of quantity? And how many variants?

 

I know you say 'not a keyboard' but what about a keypad? Have you come across "X-keys"?

Our $1000 LG washer suffers from badly lit symbols...in low lighting you can't read any of the legends, they made them using some  low contrast colors (gray/silver background).   So the led indicators move around & are bright, but you don't know what they mean.

Funny, my $2 dollar store remote control has about 60 buttons and they are all brightly backlit at the touch of the bottom button...you could almost use it as a red flashlight.

Killing some time while the virus circulates outside my house and came across this one from Dave Jones. Pertinent.
