Inside a Hori microswitch


#1

For those having problems with the Hori EX2 buttons, here are some pics of the insides:

The gold ball completes the connection for the button, so problems with it not registering seem to be because the pins that the gold ball presses into are bent out of shape, so to fix the problem you should bend them back into shape and lube up the ball to prevent it sticking and wearing out the pins.
