What is the purpose of this two pin component (circled)?
It looks to me like a jumper, but it seems strange that it would be so complex for just a jumper (that apparently does nothing). Sits between an AC input and a bridge rectifier.
Looks like a horizontal spade connector receptacle.

Leon Heller, If it was a fuse it shouldn't be labeled J14.

Is that the only component on the board which looks like that? Is there a similar looking one located elsewhere?

It's a solderless spade connector, soldered to the PCB.
Like this:

Any suggestions on why it was used there? I thought those things were for removable ground connections, which is not the case here.

@Mast, maybe it's used as an auxiliary power input for standalone testing of the board?

@BrockAdams Perhaps, but I'd have expected another one of those in the other AC track if that was the case.

@Mast, it might be offscreen. Wouldn't want 2 AC lugs in such close proximity.

Looks like you remove that part, could be interesting to see a photo of that configuration. I would guess it is for inserting a certain kind of current probe when testing, J11 designation is even weirder.
