Multiple load E-stop?

Hello everyone,

This is my first time writing here so sorry in advance if I break any forum protocol. I am currently working at a makerspace ran by my college and am building an enclosure for our x-carve. My boss would like me to set up an e-stop that not only stops the x-y-z movement of the machine but the spindle as well. Our machine has the spindle separate from everything else when plugging it in to a power source. I was just wondering if any one has done this or if it was even possible to wire everything in to the same e-stop. Thank you!

Same power source? E-stop the whole thing.
