At least she is wearing some PPE, that would help, but she's not as tough as you think. I'll soon post a photo of me holding the live and neutral wire of a 220v cable. Beat that.

I never had one of those spring-like soldering iron stands so I just used to rest the iron on a book between making joints ... SOLDERED joints!
I got distracted once and picked up the iron by the wrong end; I could swear that I smelt the burning skin before the pain hit me! I ended up with grooves on my index finger and thumb.

We're getting side-tracked but my favourite seems to be when welding, I always seem to either pick up the item by the corner I've just welded or lean on that corner to weld the opposite one.

A college lecturer did that when he was helping me with something. He was going to draw a diagram and reached out to pick up his pen but picked up the soldering iron by the tip instead...
No you didn't.
You may have got an electric shock, but I doubt that you got electrocuted.
Anyway back on topic. Don't try to solder to those tracks unless you have the right tools and decent flux, and a steady hand. The tracks will lift. As I said about a zillion posts back, follow the track back to the next component. There will be a blob of solder there, tag on to that.

The only verruca I ever had was cast into outer darkness with the help of a huge amount of oral alcohol and a needle point soldering iron.

If you want to solder the tracks (and I wouldn't even think of it), you'll have to remove the green solder resist film and expose bare copper to make the solder stick. I think you'll lift the track in a couple of seconds. Please don't try it.
The solder bonds to the copper. But don’t go there - unless you have proper flux to clean the tracks and unless you’re really skilled at this sort of thing, the tracks will lift. Find somewhere else to solder on to - can you show a photo of the rest of the board, including the “plastic thing” that hides the next component?

The bit marked W is a decent area of copper so I think you could solder to that with a bit of care. You may have to very lightly abrade it to remove any solder resist. You can cut the track marked /// with a scalpel or really small drill bit. Soldering to the pad marked W should be straightforward. I think you are in with a chance.
and there’s no need to cut the track unless you end up bridging the tracks when you solder. There should be no solder resist on it, cos it is a switch connection, but if you have any separate flux, use some.
I wonder what’s under that black plastic thing? What does the other side of the board look like?

[QUOTE 4927699, member: 9609"]if I break the route where I have drawn the three parallel lines, then solder a wire bang in the centre of where I have drawn the circle and the other wire to the existing solder- that should do the trick - or do you think the exposed copper tracks will just disintegrate ?

As @slowmotion's said, there should be sufficient copper to solder one wire to the bit marker "W". If you follow the track on the other side, it goes to a large bare copper pad on the top right hand of the circuit board. You should be able to use that to solder your other wire to. Just clean the copper (a little meths on a cotton bud will be fine) and tin both the pcb pads and the bare copper ends of the wires with solder before soldering them together. Also, use a decent flux cored lead solder; the lead free stuff's hopeless.
