The concept is that an automatically activating command block can stop itself from automatically activating, and when it does so it'll cause a chain of following command blocks to be activated.

Commands for demo 1:

(button press)
blockdata [x] [y] [z] {auto:1b}

(at x, y, z)
blockdata ~ ~ ~ {auto:0b}
[do something here]

--

Commands for demo 2:

(button press)
execute @e[tag=NoBUActivate,c=1] ~ ~ ~ blockdata ~ ~ ~1 {auto:1b}

(at x, y, z)
blockdata ~ ~ ~ {auto:0b}
[do something here]

(in your chat, one block south of x, y, z)
/summon ArmorStand ~2 ~ ~ {Marker:1b,Tags:["NoBUActivate"],Invisible:1b,Invulnerable:1b}

You'll want to have unique tags and selectors, especially if you use multiple of this idea near each other.
