I looked at several diagrams online and none of them show the casing being grounded. There are 8 pins, the middle 2 are hot and 3 connect the hot to whichever pickup is selected, each pickup coil has 2.5k of resistance and then go to ground (the switch also connects the hot to the tone pots). So I'm having trouble figuring out the purpose of the casing being grounded. I ohmed it out but all I see is the resistance of the coils.
I'm installing a second switch and additional pickups, do I need to ground the switch casing?

Hello there,
5 way switch grounded why? All the metal parts should be grounded. The ground is like a hole that static/noise falls into. Electrical charge goes in search of a ground. If you do not ground, you have a noisy guitar. Single coils are noisy enough even when grounded. The ground should make a complete circuit, but not a repetitive loop (2 ground wires to/from the same points).

Do I need to ground the additional parts? Yes. Absolutely. Those need to be grounded for the same reason the others are grounded.

It's probably just for screening purposes to reduce the amount of hum the circuit picks up. When you touch the switch (assuming it has a metal tang) any 50/60 Hz mains signal on your body will also be present on the switch casing and some of that may couple onto the conductors inside the switch.
It probably doesn't make a lot of difference, so I wouldn't worry about it.

Switch is grounded was a common practice for all circuits. Ground its case can give more safety protection if the switch is leaking in the future. Ground it or not,it up to your choice. Make no difference to the circuit, unless you are building an AF high gain amplifier and that switch is near the pre-ampl circuit. Without ground it, hum sound might take place.

the important thing about grounding is to ground everything to one point.say you have three things to ground,dont ground one to two and then two to three and then finish with three to one,this can form in some cases a loop which will pick up stray signals to be amplfied by the man amp.so ground everything to one point and you shouldnt have any problems
