Pleas pardon the diversion, but I have a Christmas electrical question: I have a bunch of left-over Carling toggle switches from building my panel.  My grandkid's toy train transformer doesn't have an on-off switch so it has to be un-plugged at the (barely accessible) wall outlet.  The transformer is 120V, 80W.  Can I safely use a Carling 15A, 125VAC 3/4HP switch on one leg of the power line?

I should certainly think so.

 If that transformer draws anywhere near 15A that's a powerful big train.

 Do make sure the terminals are not accessible.

Thanks, Ron.  I plan to make an accessory box for the switch.  - Jay

If you are putting the switch on the 110V side of the transformer, be

sure you put the switch on the 'hot' side.  (Probably a black wire

inside the wall fixture.)  If the switch is going on the train side, it

won't matter too much which wire, but the transformer will still be

pulling a little current.

Yes, if you turn off the power first!

  

 Seriously, you want to switch the "Hot" wire.   This is the one that goes to the narrow tab on your wall plug-in.  If you  look at the plug in, you'll notice that the two parallel tabs are different  sizes (if you home was built in the last few decades).  The narrow tab is  the wire that you want to switch.

  

 I don't know if Bob has a reference drawing for  this, though.  A purist would also put an in-line fuse.

Hi Jay,  another thing worth considering is to use the switch to 'break' the hot side of the line (if it is a single pole type).  This would prevent a possible shocking experience for someone who finds a 'ground' to complete the circuit.  We love our Grand Children.  Earl

Merry Christmas!

Vern,  That's exactly what I need to know.  Now I don't need that Z-drawing !  Thanks - Jay

Considering this is to be used for a kid, circuit protection, grounding, ….  

I would recommend that you get a switched power strip.   

   

Otherwise do as others have recommended, make sure everything is secured, the switch itself is properly grounded,  

and that any box you use is sturdy enough to take the abuse of kids!  

Make sure that you switch the “Hot” wire (typically the black wire) or the narrow tabbed wire.  

If this is a two wire circuit (i.e. no ground wire) I would NOT install a switch, a failure in the switch can pose an electrical hazard.

I hope this train has a junction box where  this can all take place.  The hot wire will go through the toggle switch  and the neutral wire will just connect inline as is and the ground will do the  same.  If you make a mistake it will not work but I'm sure you will get it  right because you have already built a panel for your airplane.  Just  my two cents.  Fun stuff.

I actually got a plastic "project box" at Radio Shack which made a real neat switch box.  I only cut into the "hot" wire to connect to the switch with fastons.  I labeled "off" and "on" just like on my panel.  Works just as planned.  Same for the panel.
