<font size="2" face="Verdana, Arial">I was thinking the same thing. Sense the new 186 thousand board seems to have deleted PK's post I fired off an e-mail to PK hoping he could clarify this better than I can. Hopefully he will respond to one of use or directly to the thread.

However it is no longer there. I do know there are many CPF members who can verify that this is what PK uses and recommends. I do know for sure that Al has used it for a long time now.

Guys--I did NOT mean to start a panic.
I fully believe that JT, PK, and everybody else are being totally honest.
The use of a dielectric grease makes sense in this application and I fully expect that PK will confirm that they use 759 as their favorite dielectric grease for O rings or threads.---Marc

so it's non conductive?? what is the stuff i see on my streamlight sl20 where the wires slip over the bi-pin? looks like conductive grease, can i use the stuff jtivat sold me?

<font size="2" face="Verdana, Arial">While the grease itself is not conductive it does improve conductivity between metal parts like threads and tail switches. The benefit here is that if used in switches the grease will not allow the light to come on because of build up in the switch however when the metal makes contact it will not add resistance but reduce it.
Hope this helps.

Anyone here uses Molykote 55M for his o-rings?

Jknight, this is correct the problem is that the lubricant will migrate to this contact point. Normal lubricants will cause resistance when they get to that point.

Darell speaks: This Nye goop is in-freaking-credible.

I don't rave about a whole lot of things, but these are products that deserve it. I thought other lubes were "good enough" right up until I tried this stuff. It works immediately and lasts!

The "conductive" grease (for lack of better term) kept a Kroll from the landfill. One of the many springs just wasn't conducting well enough to keep consistent 500mA power in my BadBoy. I lubed it up, and the switch is now better than new. Seriously!

I think the grease being conductive or not is a moot point. There is no electrical connection made through the tailcap threads. The electrical connection is made via a plate that makes contact with the edge of the flashlight body when you press the button. It also makes a connection when you screw the tailcap all the way down as you are forcing the plate to make contact with the edge of the flashlight body.

I’ve attached a very crude drawing I did of the electrical contact point inside the tailcap.

Please feel free to correct me if I am wrong, as I don’t have a SF with me today and I going on memory.

I've often womndered how to increase the performance of my torches' switch mechanisms. In 2w cewll torchs in particular, contact rsistance can have a really adverse effect on tfhe torch's output, parrticularly in the cae of LEd' which rely on constant current for even light output.
As I carry a torch in most weathers on my motorbike or pushbike, dampness can corode the torch's contacts as well as the contact surfaces of the batteries themselves. The lifetime of a sety of duracell batteries in an LEd torch is such that "date expired" batteries will continue to work for months even if the torch is in every day usage (I do a fair amoiunt of night walking to keep fit).
I will run a litle experiment...I'm foing to lubricate pone of my 2 cell LED torch switch contacts with WD 40 and also polish the cell ends in WD40 as well to see if constant brightness is achieved. The torch will be my Edc for a while and will be exposed to various weathers. We are expecting rainstorms again during this weekend so my torches are being primed in case of another power outage again!
