62 Starter Switch

On the left an OEM starter switch. On the right is a new NAPA “exact fit” switch. Aside from the new one needing to be modified to fit in the dash properly-it has a ground spade circled in red. The oem doesn’t have a ground spade. Does this new one need to be grounded by wire or does it ground in the dash hole??

I just replaced my "exact fit" NAPA headlight switch in my 64 with another "exact fit" NAPA headlight switch. Both had the extra ground terminal. Both switches failed. I dug through my stash and found an old OEM switch, without the ground terminal, and it works perfectly. I'm thinking you could install your switch without using an additional ground wire and it will work fine.

I suspect the same. It’s easy enough to run a wire to the dash frame to ground it too. In part I guess I was wondering it any ignition switch needs to be grounded? They work just hanging from the harness so I think not?
