Default Marconi 2955 Keypad Switches

Hi,
I am wondering if some kind person could help me with information on Marconi 2955 Keypad push button switches.
Reading through the posts on this site, I see that these keypad switches are prone to failure.
My keypad has done this and I notice by reading the posts that they are available on Element 14.
I have searched Element 14 with no success.
Would anyone have the Element 14 part number or have any information as to where I may be able to purchase these keypad items.
The Marconi part number is 23465-301.

Any help would be very much appreciated
Regards
Jim

Many years ago, I believe I use some CK swithces, type D6L90F1LFS.

However, I may be wrong. Download the datasheet from their website and check the dimensions and pin connections.

You would probably have to get these from the USA.
