Desolder the micro switch and replace it with a new one, E-Switch TS20100F070S. Some have trouble to desolder the switch. You can eventually clip the tab to remove the switch. Once the switch is remove you can easily remove the solder tab.

I use a Weller ST7 0.03" X0.79 mm ST Series Conical Tip to remove and solder the micro switch

Just remember, the micro switch doesn't have a polarity. But the connectors will guide you which side the micro switch needs to face.
