Coffee or coke spilled over. Better remove it, clean it, ...
some lubrication also, and back to place. Switch group should be pulled up.
Wrap some tape around round edge pliers (to prevent indentations to switch body), and pull from middle bar (the bar separating front and rear switches same side), pull left and right sides separately.

All the group will come up together, the best ...
way to pull it, is jumping one side to the other, pulling from the middle bar.
See picture.
