Starter/Ignition Switch

[Laurence]

Two questions.

I posted the following questions on the 356 forum but received little help there so far. The subject is the starter/ignition switch which I think early 911s and late 356s share.

(1) The starter/ignition switch (bullet connector type) in my 1965 356SC has 11 socket terminals. One terminal is labeled ' pa'. That terminal has the same diameter as the 50 terminal. What is the ' pa ' terminal?

(2) The internal contact of 50 terminal doesn't always work when I turn the key. The bullet plug has good connection but internally the 50 contact is intermittent. All other internal contacts work fine so far. When I push on the 50 wire/bullet plug the starter motor will fire-up. I guess the extra push helps the meeting. Can the ignition/starter switch internals be be cleaned and/or repaired? I can't find "on the Internet" a discussion about opening late model 356 ignition/starter switches. Or, should I search for a working switch? If searching for working switch becomes necessary, I prefer a switch like the factory-installed switch (11 sockets). Thanks for your replies.
