10Pcs 12V 20A SPST Rocker Switch with Blue LED - Waterproof Toggle Switch for Car, Marine, Boat, Truck, Trailer, RV - 20mm Round Hole Panel Mount

They seem quite small to take 20a but are perfectly capable in use.

Nice little basic pack of switches ideal for vehicle installations or low volt LED setups or any type of low voltage projects that require simple on/off switches. Each comes with a small green LED which you can have wired up to illuminate when switched on. They're pretty basic but they work and for the price you can't really complain, longevity may be an issue but at this price they are easy enough to swap out if needed.

5 of the 8 switches were fine and did the job as they should, the other three felt horrible to switch with a grating feel as they were switched. Luckily didn't need all of them. A little cheap feeling but the blue LED looks cool.

Nothing much else to say about these, exactly ten pieces arrived neatly packed into a clear self-stick pouch of a reasonable size, and they are all uniform in quality. They snap firmly from open to closed with a nice tactile feel and an audible click so you know exactly when you’ve flipped them from on to off. One minor complaint I have is that the included measurements aren’t shown alongside an image and there is no recommendation for the size of a panel hole you’d need to cut for them. I’d reckon you’d need a panel hole in the ballpark of 27-28mm by 11-12mm to give you a solid hold with the plastic tabs on either side. The current price of £6.99 is in the middle of the pack in pricing compared to many other SPST switches around these dimensions, quality and quantity. So while it’s not the absolute best value it’s also not horribly marked up, so there isn’t really much to complain about here. They’re of course far more expensive than buying the exact same switches from China if you’re willing to wait, otherwise they’re a perfectly viable option if you just need some generic rocker switches for a project without a long wait.

Very budget switches, packed in just a plastic bag which had split and was spilling out, luckily I still got all 10. All 10 are operational but I wouldn't trust them to 20A, maybe 6. The operation clicks with reasonable feel. They are relatively easy to fit as round hole types always are, a step drill is useful until just the right size hole is reached by testing the fit often, as the front 'flange' is very narrow, barely a couple mm, so any over size on the hole is going to show. What is shocking though is the switches have no markings for the pin-out on them! You need to print out the diagram on the listing and keep it with the switches for future reference. (loses a star for that). Brass terminal is 1 = common Ground, Middle is 2 = 12V supply, LED side terminal is 3 = Load. The value is hardly good, £7.49 for 10 so 75p each. These are £3 for a dozen from China, you would only be buying these if you can't wait the 7 days shipping these days. (loses a star for the mark up) At least with 10 you will have spares if they fail. Actually knowing this product, I would fit with push on spade terminals, easier to pop a failed one out and fit another.
