70pcs 12x12x7.3mm 4 Pin Momentary Tactile Push Button Switch

Absolutely bonkers bang for the buck here! I bought this giant bag of buttons expecting them to be awful due to how cheap they are — I just needed a LOT of through-hole mounted momentary switches for a throwaway prototype. I was so pleasantly surprised at what arrived that I had to leave a review. They certainly aren’t perfect, but they are outstanding for dirt cheap buttons. The bases feel rock solid once they’re soldered into a PCB, but the connection between base and cap does allow the caps to wobble under slight pressure approximately 20deg like tiny joysticks. No rattling though. They’re highly tactile and the action is pretty stiff, similar to an extra stout mouse click. I have been using six of them on a homemade macro pad for a couple of days (including for some light gaming) and so far have had zero issues of any kind. No bad switches so far, after checking about thirty of them. Important Note: This can be either a pro or a con depending on personal taste, but these buttons are EXTREMELY loud and clicky. Personally I love that about them, and fortunately so do my wife and kid. They are legitimately good as fidget clickers, by the way. Just don’t buy these for anything that needs to be quiet.

Using as part of Scouts Electronic Merit Badge for breadboard projects and 555 IC mini piano. Good sized buttons and fit perfectly into breadboard. Works as expected and great value as I can put 5 buttons in each kit allowing for 14 kits @ 68cents per kit.

Let's say you're a hobbyist electronics wizard - or working on schoolwork that requires some electronics tinkering. You could go to one of those super legit electronics suppliers if you want really, really good components. Or you can go to Amazon for some speedy deliveries. These are the speedy delivery type. The switches themselves are fairly large, making them easy to press. Very clicky. Compared to some switches, these are actually really easy to seat on a breadboard for prototyping, too. And the button tops are handy. These do their job just fine - but also remember that this sort of component won't have datasheets... which don't matter in the case of these switches. 70 switches for a cheap price, which seat well on a breadboard? Seems a win to me. Recommended if price and ship time are most important. Otherwise, spend some more money at an electronics supplier and guarantee the quality of your components.

I used 2 dozen of these 12x12mm buttons so far in my projects. All worked. All fit my PCB perfectly and the button caps fit well and were uniform in size. I will definitely buy these again.

These buttons all worked new and still all work today.

Great quality

These guys are really versatile for any prototype or project. Theyre small enough that they don’t get in the way but not too small that theyre hard to push, love these things!

Got these to replace the Omron's in my Dawn Remap kit as the stock ones start failing after a few months. Missed clicks etc. In my case it is excessive use, lots of spamming of buttons in game. Something these switches were not made to handle even with the high actuation cycle life ratings. Not to mention they are often actuated off center EG your pressing from the side vs directly. These are about twice as tactile as the omrons with the yellow stem (seen black and gray by that manufacturer so I dunno if there is a different rating per color) Knocked off a few stars as these seem to be failing now as well. I figured this would happen and was not too put off that i had to get 70 of the things. Only use 4 at a time in the remap kit. So I got plenty for the life of that pcb and to supply some custom projects or custom pc case power and reset buttons. The included buttons asre fairly cheap you can see the dye is thin meaning it is not a nice solid opaque color. Search about if you want some nicer buttons but for projects and stuff they work great and have a flange for retention in a panel.

Better than expected because on the picture it was showing a ziplock bag for the 70 pcs including buttons caps. well it came in a plastic organiser all sealed, everythings is perfect i got 70 tact switch and 10 of each colors button caps so 70, thanks you definitly will order again if needed.
