Time to grab a couple of tools

a. Wire wool to clean your connectors.

b. Small electrical screw driver to remove the back electrical connector.

Once your old switch has been removed from your loom,  lay both switches out on the table ready to swap components, like below

Lay your old switch out on the table and applying lite pressure from behind the connectors taking care not to damage the black connector
