The images show you how to build them. They are both one block wide and the bottom (upward facing) sticky piston is the piston which detects bock updates.
The first image shows my compact BUD switch design that would send out a pulse and the second images shows my compact BUD switch design that would toggle its output.

But this BUD switch is not bug free, because with some blocks the bottom piston will extend and contract to fast and doesn't take the glass block back down.
I found the following block bugs:
  • When the following blocks are placed against the piston:
    Sticky Piston
    Jack 'o' Lantern
    Furnace (also when the fire turns on/off)
    Fence Gate
    Powered Rail
    Detector Rail
    Wooden Stairs
    Stone Stairs
    Brick Stairs
    Stone Brick Stairs
  • When the following blocks are removed:
    Jukebox (while playing a music disc)
  • And when a iron door opens/closes
But with the usual block updates it works just fine. Such as glowing redstone ore, or when a torch is placed on/removed of the block adjacent to the piston.

About the retraction bug.

I think the block interactions you mentioned all involve two consecutive block-updates ( like a lever which is placed and then immediately propagates it's off-state )

It seems likely that the second update is so close that the final pulse is one or less ticks long, since sticky pistons toggle with short-pulse widths it would seem to explain alot.

Thanks again, i hope you are still crafting out there somewhere.

I did some "research" to way to fall trough floors (like this), I found at least 15 ways to do so, but did not have much time to make in to a proper post.
