Slide Controller override switch replace?

The rubber / plastic button actuator on my Schwintek / Lippert slide controller was knocked off. I want to replace the switch indicated by the red circle. Has anybody done this? What switch did you use? I found one on Amazon that looks the same and is about the right size 6x6x5mm. I don't want to spend 100s on a new controller because this one works except for the button.
