Electrons flow quickly from an area with relatively more electrons to one with relatively fewer electrons. In order to flow, electricity needs an entry point and an exit point, and there has to be a difference in charge between the entry point and the exit point. In order to understand the function of a ground and a signal in a switch and its device, you have to understand a few things about electricity.įor electricity to do its work, it has to flow the movement of electrons is what usually gives electricity its effect on things. While this wiring concept is simple, implementing it can be more difficult as you can see by the size of this section. Wires and connectors, solder, and/or twisting are used to link the devices to the PCB.įor quality PCB wiring, the main goals are having required signals covered by the PCB, corresponding ground and signal connections and circuits, solid and secure connections, connections that will not cross or interfere, insulation, and some level of organization.
Each device has switches when the switch is engaged, a circuit between the ground and signal should complete and send the signal from the PCB through a cord or remote to the computer or console. The simple goal in wiring is to have the grounds and signals of each device linked to the ground and desired corresponding signals on the PCB. A PCB from another source can be used in replacing the electronics in a standard device, or giving communications to a custom controller.
