1. What is lubing a switch?
Lubing a switch involves coating the switch's stem, the part that makes contact with the inner housings of the switch, with a nonconductive material, usually oil, grease, or a mix of the two. The result is that the switch ends up feeling smoother on its travel.
2. Do you sell stock, unmodified switches, along with your pre-lubricated switches?
Very sparsely, I'll hold pre-order periods for stock switches when I'm ordering in bulk. I try to keep the cost as low as possible for the customer. However, this may not always be the case, as these pre-order buys end up costing me more in international shipping by adding onto the total weight of my order.
3. What lubes do you use?
I use Krytox GPL 104, 105, and 106 in various mixes, depending on the switch. These are premium, top-of-the-line, pretty pricy lubricants that will last in your switches for a very long time, and since there is only one substance (oil), you won't have to worry about separation!
As of August 2017, I use Krytox GPL 203 GRADE 0 and GPL 204 GRADE 0. These lubes were made for me by Chemours and Miller-Stephenson, and are a perfect balance of application ease, price, and performance.
5. Where do you lube?
I lube both sides of the stem, where they hit the bottom housing on the sides, the hole where the stem goes into as well as contact points for the spring. On linears, I will also lube the legs that hit the contact leaf, but on tactiles, I tend to stay away from it because users report dulled tactility when I lube it.
6. How long does it take to lube a switch?
About a minute each, but it varies by switch. I'm really practiced at this stuff, and I'll very commonly QC along the way, so it usually ends up taking about an hour for 45 switches or so!
7. What happens if a switch arrives and is broken?
This can always happen, due to either factory error, my error, or shipping errors. Contact me at Krelbit@switchmod.net, or PM me at /u/switchmod_keyboards on Reddit. We'll sort something out.
