following on.

the phones substantial amount of unused space can be taken advantage here and the backing panel could be taken off, incorporating the metal contact plates. one inside the phone and the other set into the back panel.

there is a slight gap between the two and this would be perfect to use as this would mean slight touches instead of forcful presses.



here is a rought conceptual idea using a negative of the line drawing and the incorporation of a sheet of aluminium.

Some handsets come with a metal case/fascia as standard which would be even easier to install this morse code feature.

Also most andsets are designed for in hand holding,the curves of the phones are designed to sit nicely in a hand, with easy access to the whole phone.



this using the previous picture can be shown fitting almost perfect in a hand. This would also enable the user to hold the phone from anywhere and be able to input using the metal sheet contacts. Even using an index or middle finger around the back of the phone.
