Placement of a power switch in a power supply

[budjb]

Switches in a DC circuit are easy enough, but I'm wondering what the correct way to place a power switch in an A/C circuit is.  I'd like to build the power supply here:

But I'd like to add a switch to turn the unit off even though it's plugged in.  How would I do this?  And must I use a switched designed for A/C current?

I've dabbled a bit with DC circuits, but have 0 experience with AC ones.  Thanks for the help

always be extra cautious when dealing with the AC side of things ...

If using a 3-wire cord, or a polarized 2-wire cord (one that has a wider blade than the other), put the switch on the 'hot' side, typically the black wire (in the three wire cord) and in the case of the polarized one, follow the wire to the narrower of the two blades. if you elect to use a fuse holder, put the switch before that as well.

I'd also recommend heat shrinking the switch lugs ...

Yeah AC scares me a bit, but this project won't build itself   I'm going to triple check every connection before even thinking about plugging this thing in.

Thanks for the response, that makes sense.

Any suggestions regarding what type of fuse holder to use?

One that is stamped with the UL and/or CSA/TUV/CE safety certification symbols.
