This is a follow up for the previous thread I posted.

Im looking for a keypad, that has at least 24 keys (my application requires 24 keys), but it would work out with a 32-key pad, or even 2 separate 16-key pads. And I need the buttons BIG to help the partially sighted (that's the whole point actually). The whole application is meant to help blind people.

Does anyone has a sight, or know some particular manufaturer that has something like my requirement??
