I received my used Yankee Turnflex 730/6 turn signal switch on Saturday. I bench tested it and it looks like I'm good to go. When I opened up the switch for some clean-up, I noticed it was bone dry. Should there be a lubricant on the moving pieces, and if so, what do you recommend?
A tiny bit of silicone grease on pivot points if you want to lubricate. Also if you can put a thin layer of silicone grease on the contact points it will keep the unit working fine for a very long time. Just don't use more than a bit. If you don't have that, wheel bearing grease (the kind made for disc brakes) is good...high temp, doesn't dry out and resists spreading. Good luck.

handyandy If there is ANY plastic would use light coat of silicone ignition grease,which wont soften the plastic. Itt's also great to use on door latches of your house so they don't clash when it's cold and dry. Oh went to my 55 year go to junk yard,found a 7-wire guide turn signal switch installed it,didn't have all the functions so soaked it with tuner cleaner (get that at Frey Electronic store) fixed it right up is fine today. My electronics pal would spray a giant PC board with that (power off) then say OK lets eat dinner (noon) turn it back on take off and work !! He would look for trouble by watching for what we called lighting (broken solder joints) solder em back fix it !! I guess you know to use silicone grease on light bulbs to hold down corrosion and keep out salt water.

It has been a few years, but the last time I went to a Radio Shack store and asked the clerk for "contact cleaner" he thought I was asking for something to clean contact lenses.

Radio Shack? I thought they went belly up 7 or 8 years ago.

When I bought this on Amazon it was less costly but that is another discussion entirely. If you need pure silicone lubricant of the highest quality (food grade, actually), you can get a 4 oz container for less than $20. That is enough to last you the rest of your life in most cases.
