Machifit DC 5V 19mm 4 Pin Momentary Switch Led Light Metal Push Button Waterproof Switch
A part of the review has been auto-translated.
I ordered a couple of these switches to try them out. Arrived safely but no padding used in package. LED a nice blue colour. The retaining nut is quite loose on the thread so not a precision fit Measures 18.8mm diameter over the threads and 21.8mm diameter over front flange so your hole needs to be 19mm. The included O ring is enough to allow the nut to pull up on the threads. The button depresses just over 2mm and the led lense moves with the button giving a 15mm diameter for your finger to press. These switches were suitable for my project and I have ordered more.
Bought 4 to test them. They are amazing. Outstanding quality, really nice feel. Looks durable and pinout clearly indicated. Will soon buy a few dozens of them
Look great in my Arduino project 👍
I bought these switches to be used in conjunction with my sonoff devices and it was meant to replace my wall switches. As a wall switch replacement the size is perfect. The switch has a little weight to it, meaning it in no way feels fragile, cheaply made or flimsy. There was only one thing wrong with the batch that I got. I used a 5 volt power supply to test the lights on the switch and got some lighting brighter than others, even those of the same color.This led me to believe that there was a mix up somewhere and I got a few 12 Volt switches mixed in It isn't every day you come across something that meets your expectation much-less to surpass them, the minor mix up was in no way a deal breaker for me. I can honestly say "highly recommended".
According to the announcement
It catered to my needs
Very good quality, metal feel, no plasticky parts.
Still to try but that's exactly what I was looking for
Works fine, nice anf bright. Takes quite a bit of force to activate.
Button looks great lit up and embedded in a case.
