Review on DIYhz Waterproof Momentary Push Button Switch 12MM Normal Open(NO) Mini Micro Switch ON-Off 125V 3A Red Black 14PCS by Cameron Reed

These pushbuttons are similar to other rounded 12mm pushbuttons I've used on various projects in the past. They are primarily made of plastic with plastic threads and metal nuts and washers. They'll all be thrown in the bag, and many of them won't have any nuts, but they're in the bag, I'm not missing anything. There are 7 different colors in this pack, 2 of each. Except for the color, they are all the same and all feel the same. The switches themselves work great and are reliable enough to be used for hobby purposes. I used them in my latest button box project so I have lots of buttons to click. They can also be used to create a mini arcade, all you need are cables and some kind of USB controller. Your quality is good. I have used several styles of these rounded knobs and they are all the same whether you have them cheap or not because they all seem to be made in the same style. The buttons are normally open, press to close. There is no way to change them to NC, they are designed to create an open circuit when not depressed.
