The E-stop button kills the power to my Shapeoko, router, and laser. The green button on the right is used to turn power on/off to the Shapeoko, it glows green when the power is on so I don’t forget that it is powered up. The key switch turns on the router power if turned to the right, or laser power if turned to the left, both are off if the key is in the middle. It’s really nice being able to turn on/off the router/laser from the front of the table. Take the key out and nobody is turning on the router/laser without digging through a scary amount of power cables tucked under the table top. For my J Tech laser I installed the red button on the right, that is wired to the remote reset on the J Tech controller. You press that after turning on the laser power to enable the laser. I split off the 5V for the laser fan to power the light inside the button so it glows red when the laser is ready to fire and I had better have my eye protection on. That lighted button is from here:

And of course the all important fire extinguisher is on the far right…haven’t needed that yet, but have come close!
