The way that you guarrantee contact reliability is by forcing current to flow, every time the contact points are moved. This causes microscopic welds.


But when I have 10Mhz broadband signals with 700mVpp amplitude I probably
can't weld them together. Or is there some trick even for this situation?

Somehow you have to force a DC current of perhaps a few amperes. This only needs to be done for a short period of time. Less than 1 second.
