Crumar T1 Key contact spring

Crumar T1 Key contact spring

I need to replace 5 key contact springs but there are not anyone available on the Crumar T1 spare parts page on Syntaur.

I did find Part #12560 and #2514 that looks possible. Unfortunately they don’t have complete specifications

I have measured mine and they have the length 30 mm and 1,3 mm thick, but I think similar measures will work as well.

Does anyone know the specifications of Part #12560 and #2514?
