       Does anyone have experience with mounting SMD buttons through the PCB? My biggest worry is the pads eventually ripping off.I would like to do it this way to try and minimize the height of the button. Unless someone can recommend a shorter one with the same plunger in a 6x6 mm.

       It looks like usually reverse mount switches have pins on the top so the pads tearing off is not an issue.

       @arturo182 Doesn&#39;t this become a greater problem with the pads?The pressure will on these switches try to lift the pads from the FR4, rather than acting as a cushion...

       @niclas @arturo182 I&#39;m trying to figure that out too — are these meant simply to be inset through a big square cutout for the whole package? if just a circular hole for the plunger part (pushing the switch body *away* from the board) then that does seem mechanically sus?

       @natevw AFAIK, it is meant to be mounted on the opposite side of the board, with the drill hole for the button, to lower profile and more importantly limit double-sided SMT mounting. LEDs are available for this as well.The answer lies in the T&amp;R orientation, and I bet the button is facing down inside the tape, although I can&#39;t confirm that right now.@arturo182

       @niclas @natevw @arturo182 Right. The Adafruit description indicates the switch is mounted on the opposite side of the PCB from where the button is pressed. So just the button - not the button chassis - goes through the hole in the PCB. Key text, &quot;That means that if you have a classic 1.6mm thick PCB, the button top will rise 0.4mm over the PCB plane. If you need more height, a 0.8mm half thickness PCB will give you 1.2mm of height above the PCB plane.&quot;
