alternative switch color

[XORadmin]

hope it's okay to bump an old thread... but my "sequencer/mark" button is no longer working properly, from normal use. I was thinking maybe I can try to remove the panel and try to clean the connection and replace the switch if necessary? But this thread seems to indicate that this might be harder than I originally thought. Any advice for me?

If you can solder a bit then it is for sure possible. 

The issue is more about cap replacement since you need to bend the plastic of these oval buttons and it is easy to bend them too much.
