Notes
This is some kind of panel switch with a non-removable hinged keycap (I bought a few on a whim).There are four terminals. The pair closest to the centre is permanently connected. Three of the terminals form a changeover arrangement.
The keycap stem presses down on the centre of a helical spring, which buckles and causes a bar to snap between touching a contact at the top, and a contact at the bottom. This snap action emits a click. The keycap itself attaches to a horizontal bar which itself holds one end of the helical spring where it exits the case.
The various pieces that form the shell are glued so effectively as to form a single plastic block that cannot be disassembled at all.
