Lubing slide switches on LED models? (Spice, Woodstock, Classic, etc.) Message #1 Posted by Karl Schneider on 19 June 2002, 3:15 a.m.
LED-model gurus --
I have three HP-34C's upon which I am doing some minor repairs, including lubricating the ON/OFF and PRGM/RUN slide switches. The switches carry metal spring jumpers that span two broken parallel circuit "tracks" (for want of the proper term) when the switches are moved to the right. I noticed a pasty yellow(ed) residue of the original lubricant on one unit, but often there is little lube left, and the switches slide roughly. (Good thing the HP-41C and Voayger models did away with them for good!)
What would be good lubricant for these switches? I have bought a thick, clear "Lube Gel" from Radio Shack (p/n 64-2326) which is conductive enough to work just fine on the sliding ring connection for my car's horn. Does anyone have a better idea?
Thanks,
-- Karl
