To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
As another reviewer mentioned, normal soldering can destroy these things pretty quickly. All tested with normal action OK before soldering. I soldered wires onto two of the buttons. The actions on these buttons were no longer smooth and would sometimes get stuck in the closed position. Presumably the heat running up through the leads heats the plastic internals and warps them. I believe I was careful to solder *quickly*, but these buttons appear to be extremely sensitive to heat. I managed to get a third button working by soldering very quickly.
These buttons are very well made and good looking. After reading several reviews that mentioned meltdowns during soldering connectors I had some doubts about the purchase. I soldered several of them to 25 gauge stranded wire connectors and had no problems. I'm pleased with the overall outcome after mounting them in a plastic box that holds the entire circuit. I will buy more of them for future projects.
However, I did follow common precautions for temperature sensitive parts - pre-tin the wires, use thin solder wire with rosin, and a hot soldering iron so that the operation can be done quickly. I would say: "not for soldering rookies." The buttons are indeed made from plastic are potentially very easy to melt by a longer soldering operation.
Works as should and would like to say to other reviews that, you can't put any soldering iron over 40watts on this switch. Take care that you tip the switch pins and wires first with a little soldering, then you can solder the wire on to the switch quickly without damaging it. I do recommend
Took me 5 switches to find two that actually worked. Could be the heat sensitivity mentioned in other reviews as I didn't test them before soldering. The high defect rate and hassle of re-soldering due to failures makes these buttons a poor value. Won't be buying them again.
These work well for me, and I like the color selection. I had no problem with the plastic melting while soldering, just be sure to tin your work first and don't linger with the iron. The switches are great for Arduino/low voltage projects and are small enough to put most anywhere. I would have to say they probably won't take much abuse, but they are inexpensive plastic switches so that's to be expected.
Extremely weak to heat. Had to melt 4 of them before soldering one properly. Simply holding the iron to the leads for a second melts the inside, and definitely makes it useless. Unless of course you want to just twist wires around it, in which case you might as well just take two pieces of wire and connect them by hand to do the same thing as this switch instead of wasting money.
Ordered this 12 pack of switches for a project that required 12 switches. 3 od them were defective. Two were misthreaded and couldn't I couldn't get the nut on. The third one was simply defective. A normally open switch that wouldnt close. So a 25 % failure rate. Simply not acceptable.
