[Boatanchors] Old toggle switches question

[Sudipta Ghose]

Inside these switches used to have a roller. The roller made contacts.
Can be cleaned and reassembled. IMHO.

I noticed what looks like tar-filled holes on the backside of some of the switch bodies. I'm thinking I can clear that and clean up the contacts. But I don't want to start hacking at the switch unless it really is simply a filled hole that can be refilled.
