Aside from the power button on the front, my pc tower has a power switch on the back. If the switch is not on, the power button on the front doesn't work. When the pc is shut down, but the back switch is on, a light shows on the front. If the pc is shut down, the front button will not work again until the back switch is turned off for a few seconds and back on.

I'm mainly just curious about the purpose of the switch, but it can also be a pain sometimes. The switch is in a cramped spot to reach presently. I would leave the back switch on, but the fans don't run when the computer is shut down, and I can feel heat. Don't want it overheating and frying something.

So...what is the switch even for, and is there a safe way I can set it up so I can just leave the back switch on and control the power with the front button only?

The back switch controls the flow of electricity into your computer. Using the front switch simply turns off the computer, but there is still a current available. Under normal circumstances, there is no reason to use the back switch at all.

The problem is, after shutting down, the front button won't work again until the back switch is turned off for a few seconds and back on.

Sounds like a failing power supply to me. I've had those symptoms a time or two. A new power supply fixed them. It's possible that it's something else, like something in the motherboard, but the power supply seems most likely.
