On And Off Switches - I/O Which One Is On?

[Chili Palmer]

I just got a new water cooler for my construction trailer and it's got the I/O symbols on the switch for the hot and cold on the back of the unit.
I can never remember if it's the I or O for on. I looked it up and it's the I. This is based on digital code of 1's and 0's, the easy way to remember is "1 is more than zero".

I just learned something today and I'm sharing my very important discovery with you people today so when you're sitting around drinking your beers with chips and salsa you too can share this important piece of trivia that will people will actually use.

O = Off
I = It better fucking work when I flip this switch or I am going to (1) get another beer, (2) throw something, (3) return this piece of shit, (4) refer to #1

I always associate I with ignition.

I = circuit in
O = circuit out
