I have been cleaning a PDP-8/e front panel and some of the switches
are not as free as others. The switches are simple slider basic
switches. I have taken similar switches apart and noticed that there
is a brown/red grease on the contacts.

Any suggestions on the proper grease for a low voltage contact.
