Finally got the switch yesterday and installed. eBay listing said it was a latching switch but it ended up being a momentary. I wasn't able to put the switch on the side like I wanted since it was too long and wide and would interfere with the GPIO pins.
This was really the only place I could put it.
I have the led ring setup to be on when the pi is on and off when power is off.
For anyone installing an led on their Pi 3+, I found that pin 8 (GPIO 14) used for power is set to low(power off) by default on newer versions of the OS, I'm on Linux 9 stretch from the image I got with 4.4.1. To enable it you need to add the following line to /boot/config.txt
enable_uart=1
