MA17 - Q. How do I clean the connections on my MA17 Speaker Switch?
Answer:
The MA17 has “self-cleaning” contacts, which usually means that there is a wiping
action as it opens and closes, rather then just a straight open and
close so that whether it be made from phosphor bronze or nickel plated
beryllium copper, it will tend to remove any sooty deposits or tarnish
as it is operated. Even so, after a long period of non-use, it might be
necessary to clean such a switch.
We recommend using
Servisol Super 10 Contact Cleaner, or you
may also find that WD-40 works as it hangs around for longer
when the DeOxit types have evaporated.
