I bought these because the Qi wireless chargers I bought for my iPhone buzz loudly when plugged in and won't charge the phone. The manufacturer replaced it and they buzzed too. Apparently that's a thing with cheap internal components. They work well but are buggy. I didn't think it would stay on 24 hours a day, 7 days a week, but it was a pain to constantly unplug it. These switches make it easy: turn on to charge and turn off when you're done. They work great. The button is illuminated when switched on, which is very convenient. I have an old one that doesn't, so you never know when it will skip power and when it won't - unless you mark it, which I should have done with a marker - those switches aren't needed because of the light. Great prices.
