Power switch for Pi 3
CASUSMC0311:
Hello all, this is my first post. I tried looking around and finding an answer before I posted and was unable to. So here it goes. I decided after watching my friend build a Coleco mini donkey kong I was going to build a unit myself. He is helping me however, I just wanted to see what ideas everyone has. I am modifying an icade cabinet and equipping it was a raspberry pi 3 and a 10.1 inch screen. It will be Mame, NES, SNES and Genesis equipt. I had to modify the cabinet a little for the screen to fit but it looks great. I am debating whether or not to place a power switch on the back, or just run a micro usb off the unit to the wall. I saw a unit on ebay that had a lighted power switch and it looked great. I tried contacting the seller but he will not answer me. The problem I am having is that I cannot find a toggle switch with a cord that will run 5V. Does anyone have a website or a suggestion on fabricating one? Thank you in advance.

Hi,
probably not what you're looking for but I got 1 of each from banggood.

and

I use them with my Pi power supply.

Thank you for the response. Those seem to be the only ones I can find as well. I'm wondering if I can just find something at the hardware store and splice in some different wires.

I've heard that you can solder a momentary switch into p6 header on the raspberry pi, and with a simple bit of programming you can get it to shutdown and restart your pi. Haven't tried this myself though. You could connect the led wire of the momentary switch to pins 1 and 6 on the gpio of the pi, to give you a power light...

You probably want to use something like this https://mausberry-circuits.myshopify.com/products/shutdown-circuit-use-your-own-switch powering the Pi off by just cutting off the power could corrupt the SdCard.
