I designed this little bracket to let me mount a Sonoff Basic wifi switch to a 35mm din rail. Mount the Sonoff to the din rail bracket with (2) #4 sheet metal screws that are 1/4" long. After the Sonoff is mounted to the bracket you can snap it in place on a din rail from the front. It won't come off the same way. You will need to unscrew the Sonoff from the bracket. Then if you still need to get the bracket off the din rail you can flex it a little and it will come off that way. https://youtu.be/mLYcEiFPLYo
