What component would you use for a 10A/115V jumper header (I need the user to be able to choose among a few power settings)? I have relatively small space on the PCB and I am also trying to be reasonably cheap.
Electronic – 10A/115V Jumper

0.156" (3.96mm) header with a female connector with jumpers in it is one way. Ratings by Molex are as much as 13A. You'll have to check that the clearances meet the requirements of whatever safety standards you have to meet.

You could have different female connectors with wires looped between different pins.
If the clearances/creepage distances are insufficient to meet the safety standards you can slot the board or skip a pin.
