Check the wiring is intact. Send m119 with the switch pressed and not pressed see what result you get.

Often this is an issue with axis being backwards and endstops being setup as mins or max's incorrectly

things to check. When looking at the front of the printer.

X+ moves head right, X- moves the head left. X min endstop is on the left, max on the right
Y+ moves the bed forward, Y- moves the bed back. Y min endstop is at the back, max at the front.
Z+ moves the head up, Z- moves the head down. Z min endstop is down and max is up.
