These joysticks were much more reliable and made a an obvious click when moved. Inside you'll find four open micro-switches on the circuit board. The Plastic of the jostick grip pushes on the spring, which in turn flips a metal contact.

The fire buttons inside the grip are the same, clean these the same way if necessary. When re-assembling the grip, be careful of the wires in the centre column, it's very easy to rip these apart with the outer side that goes through the two holes.
