The tayda switches usually WORK just fine. They do what they're supposed to. The problems with cheaper switches tend to be that the epoxy melts at a much lower temperature and for some reason the metal used on the lugs doesn't accept solder as readily, both of which result in melted switch contacts and less reliability. I've also taken the switches apart and the plastic rocker inside the smallbear ones is thicker plastic (also the Mountain switches) and the metal on the contacts also seemed to be slightly thicker. This is inside and you'd have to do terrible things to a switch to make it relevant, but I think it's reasonable to say that the switches are less durable.

But it's the solder thing that worries me. They don't make great contact which is especially bad when you are soldering them directly to a board, and you're more likely to damage the switch while just trying to get the solder to adhere. Ask yourself if you enjoy desoldering DPDT switches from a PCB and whether that's worth a a couple dollars.

I had same issues re taking solder—I stopped trying to use them.

Just a heads up to make sure you check the pinout manually if you order an on-on-on switch from somewhere other than Smallbear. I have used a Tayda switch in the past and I *think* it's the same, but I have also ordered other switches from ebay and found that the connections for the middle position are different. That is, following the smallbear diagram, some DPDT switches connect lugs 2&3 and 4&5 in the middle position. If you are board mounting a switch, this is extremely annoying. If wiring off-board you can adjust your wiring to accommodate but it's always good to test with a multimeter first since it's hard to find datasheets on the cheaper switches.

Well I found a diagram from an old ebay listing that said they had the same pinout but will double check fro sure as it is going in a pcb. Midway, I sent your youtube video demoing the nautilus to the guy I am building this naughty Fish for so iti is interesting you posted on this. I've had the same experience with tayda blue switches, so I know better. Gotta be quick soldering them and not overtighten them. My experience has only been with the blues switches, though. I don't usually have issues with the reds, though I am still careful and quick with them.

Thanks guys!!
