yeah that looks pretty roasted. it's still fixable, though it will be more difficult now.
the copper pads that the two pins are gone now, so you would need to either carefully scrape off the black shielding layer of the copper traces that the copper pads used to be connected to, and solder the switch pins to those as well. alternatively, you could determine where the traces connect to, and solder a jump wire to those points instead. unfortunately, this PCB design uses just the two switch pins to hold the switch in place, so you may have to find another way of securing the switch in place
additionally, as mentioned, it looks like you've resoldered two LED pins together above the switch hole, which should be separated
it looks like you may have also melted the A key's LED plastic as well, so that might not work now
