Inspect the metal pins at the bottom of the switch to see if they have been bent out of shape.
A working switch should have straight pins that fit into the circuit board. If the metal pins are bent, straighten them by hand or with pliers/tweezers.
This step alone may fix the switch; proceed to Steps 7 and 8 to place and test your switch.
