Signal wire connects from your button to your joystick controller to your PCB. A ground wire accompanies it to regulate electricity so you or another sourcce doesn't become part of the conduction. Unlike signal wires which must be separated to reflect the exact button being pressed, ground wires can be daisy-chained together. This solution is now available as a 3 connection wire.
Each connection point contains a .110 quick disconnect and nylon sleeve. A 3 connection daisy chain is perfect for your home or guide, start and turbo buttons of a custom or commercial joystick.
