	Wiring of switches is generally '''normally open''' with '''ground ~~source~~'''. The switch is wired to ground on one side and the controller board on the other, and when pressed, it connects ground to the controller, registering as '''closed'''.

	Depending on your controller, you may or may not need a '''Diode''' connecting the two leads on your coils. The reason for this diode is that when a coil's magnetic field collapses when power is stopped, it produces an in-rush of current in the opposite direction - a '''Flyback''' voltage. The diode is there to shunt that back into the coil to avoid damaging the transistors.		Depending on your controller, you may or may not need a '''Diode''' connecting the two leads on your coils.

	''P-ROC'' and ''FAST'' controllers do not need them as they have built-in flyback protection, while ''OPP'' and other original manufacturer boards do require external diodes. Make sure to confirm the need for diodes prior to wiring a game.

	For this reason, it's recommended to use direct LEDs ''under'' the playfield, while you can use limited strings of serial LEDs ''above'' the playfield. However, some manufacturer (notable Stern and JJP) exclusively use serial LEDs in their newer machines (2013 and newer). They probably do that because of lower costs and reduced wiring. Admittedly, JJP had problems with that in their first machine (WoZ).
