Taking apart the switch is simple as it is removing it. It is putting it back together that can be a pain in the rear! The slide pushed on a rocking brass piece that makes contact with the tabs the pins are connected too. It is the tab that corrodes if something was poured onto the keyboard. They usually last forever under normal use.

There are two tabs on the side that you press in and the switch pulls part like a space shuttle pulling itself out from dock at the space station - literally! Just take it slow when you do or the spring will fly out and get lost. To taunt you, it might even pop out and hit you in the face before running away!

Another design of the switch, there are tabs a the bottom that need to be pulled out before the switch can come apart.
