The joystick on my Galaxian stopped working and won't move the ship to the right , moving to the left still works though . Can the leaf switch connectors get corroded and stop making a connection and need to be cleaned ? Cold solder joint maybe instead going to the leaf switch ?
 
Yes they can get coroded. Clean with a business card NOT sand paper as sand paper is too harsh and can damage the contacts. To test if its the switch, run a jumper across the 2 wires that go into the switch....

running s jumper wire is a cool trick , it helped me determine that the switch was fine but the problem was something else . Turns out the edge connector on the Galaxian PCB was dirty , just like a Nintendo NES cart . After cleaning the edge connector the joystick now works .
