Helunsi 5 Pcs Inline Switch, Cord Appliance Black Switch, Button ON OFF for Lamp, Rated 10A 250V, Replacement Repair Control LED Electrical Extension Cable Wire Plug Light Wiring - With Indicator Neon

I purchased these switches to replace a failed switch on a resin UV light. The only reason I purchased a 5 pack was that a single unit was $4 and if another switch fails I'll be ahead.Installation was easy enough and involved snipping the old wires, stripping, then tinning the ends with solder. Loosen the four internal screws, insert tinned wires, tighten screws, replace cover, then insert and tighten the four external screws. All told it took about 10 minutes to complete.The switch seems robust enough. It clicks open and closed easily enough. For these light usage applications they work fine.

I used three of these to replace the cheap rotary cord switches that were on my lamps. These are easier to use and look nicer too.Oddly, the package says 10A 250V but the switches themselves are labeled 2A 250V. The switch contacts look big enough to handle more than 2 amps but it didn't matter to me because I only needed 1 amp, maximum. The switches are labeled as complying with the EN/EC (European) safety certification, which is slightly more strict than the safety certifications here in North America.These are double-pole switches that disconnect both wires when they are off, so they are safer with respect to electrical shock hazard.Wire connection is easy via screw terminals. The terminals are big enough for #14 wire. If your lamp cord is #18 or smaller, you have to fold-over the wire ends and then put them in the terminals to get the screws to clamp tightly onto the wire.Once installed, the switch has a nice solid feel with a strong click.

My mother inlaw had a candle light for xmass and she had to unplug it to turn it off. I put one of these switches inline and she said its so nice not having to bend over to unplug the light. Easy to install, solid construction and looks good when installed.

It's small. easy to install and working great so far.

Very nicely made, easy to work with and work as they should. Tip: Tin the ends of your wires prior to inserting into the switch for better contact and fit.

Overall a very good value and good quality switches. Two small issues you should be aware of: 1. The wire connections are very small and require a small slotted screwdriver to unscrew the terminal screws. You insert the wire into a very small hole below the screws. Holding the whole switch and tightening the screw is fussy, but not a huge deal. 2. There are 4 Phillips Head screws that hold the cover on the switch. Requires a small Phillips driver. 4 screws seems excessive and they are hard to thread since the screw holes are not threaded. Again, not a big deal, but the screws are soft and easy to strip out. Bottom line -- good switch with a slightly fussy install process.

This review is for the black switch. To clarify some contradictory info in the Customer Q&A section:-- The black switch does NOT have an LED (in my case good)-- The back of the switch is bowed, not flat -- yet, I've had no problem with it sitting upright and flat on a surface such as a night stand, desk, or even sofa arm.I ordered a bunch of other in-line lamp switches, and these are the only ones I kept. Here's why:-- HOUSING --The 2 housing pieces are screwed together with 4 screws, instead of just snapping together permanently. This means the switch can be disassembled, re-seated, removed, or reused. Because of the screws, the housing also clamps the housing together much stronger -- you'll need this if the plastic sleeve of the lamp wire is slightly hard or slightly/thicker over-sized for the hole at each end of the switch (which happened with 2 of my lamps, all low-current devices rated for 60 watt or less bulbs, so I'm not talking about heavy gauge wire -- just a plumper sheath).-- WIRE TERMINALS --The wire terminals also have screws. This assured a tight fit and the wire can be re-seated or redone with ease, and easily adjusts to different gauges. Not necessarily the case with crimp or snap terminals.--TACTILE FEEL--These switches just feel nice to hold and use. The shape is sculpted instead of being bland and rectangular. The varying matte/smooth finish feels nice.For my application, all of these features made this switch feel higher quality in every way than others I tried. Glad I found them and would expect no problems going forward unless the actual rocker switch mechanism develops problems, in which case I'll update this review.

Once you figure out the wires slip easily into slots under the tightening screw, hooking up the AC is a breeze. Getting the cover back on has yet to be accomplished. Four TINY!! little screws secure the cover on after you connect the wires.Too much resistance for jeweler's screwdrivers, and the Philips heads way too small for regular screwdrivers.If I figure out the secret, I'll post an update.I gave it a ★★ because the first part is easy - I'm holding off on the others until I see results on closing the casing.I BELIEVE i FOUND THE PROBLEM - the opening for the wire to pass through [top and bottom]. Only very thin AC cords will close the fixture completely.THE VERDICT: make sure you plan to use on a very thin gauge wire. Most AC cords use 16-14 gauge wire [the smaller the number, the fatter the wire], I may have the larger 14 gauge and this maxes out at 16 gauge. I got it to work, but there's a gap around the fixture.Caution: "14-gauge are used for light fixtures, lamps, lighting circuits with 15 amps."

Wiring is good but the switch mechanisms suck.
