Hi good day to you,
im also attempting to fully restore an MX Revolution, i have 3 - thats how much i love these mice lol
One is bluetooth and 2 are RF Radio Tranceiver types.
The one im repairing now and doing a teardown with, which ill post on my blog at some point, is the RF one so not the bluetooth, but BOTH are almost EXACTLY the same inside except the bluetooth transmitting capability and also some battery mount/connector types are slightly different.
Here are some METAL push buttons for the replacement you seek, plastic ones are below too, no model numbers, but these are simply referred to as “Tactile Switch Buttons, 4-pin“ those are the magic keywords you search for and you’ll see many of this type;
