what is a micro switch on trucks used for?

I often ponder what the hell a micro switch does, then I realised, it is easier to exclude what it DOESN'T do, and I'd get there eventually

Sooooo....

It doesn't give lesbian haircuts.

Or stop people doing really stupid things.

It might be that thing that made everyone in the 80s totally rad.

But if that is the case, then it definitely wears off by the time you hit 1995 and/or made your wife get a bowl cut and accompany in you glamour shots.

Maybe these cats have micro switches? If so, they should activate them NOW and get all ninja cat on this freaky couple.

Oh, that's it!!! A micro switch is what is installed in trucks so that when ever this guy takes a photo of himself looking all bad ass in his mum's lipstick and uncle guido's chain... a truck will smash through his bathroom and destroy the evidence, because if this dude was allowed to keep taking photos like this the world would explode and scientists will look back and say "well there was clearly too much awesome floating around".

You see! The world is now safe thanks to microswitches.Well, why are you still reading this... fag!
