I use several power strips that are plugged into separate switched outlets using double electric switch gang boxes having a light switch to turn the outlet in the second gang, I have my controller, lights, and cooling fan on one and have my exhaust fan, laser PS, water pump, gauges on another switched gang. It is wired so that the the laser PS group can not be powered up without the circuit with the water pump and fan and controller powered up. I have also wired a safety switch to shut my laser off without cutting power to anything else.
