Using my iFixit tweezers I carefully lifted the black tabs of the switch and the top half of the switch could be lifted off.

The switch contained two springs and a small copper pole. Upon inspection, when the switch was pressed, the main spring compressed and held the switch pole down, but the pole was not making contact with the "throw" (one of the spade connectors).

It appeared that the pole might have been bent slightly from its original orientation. My fix was to slightly bend the pole to ensure that it would make contact with the spade connector as designed.
