A regular light switch might spark as you flip it, or a power switch on electronics. Some electronics use a spark gap as a form of surge protection: https://en.wikipedia.org/wiki/Spark_gap#/media/File:PCB_Spar... None of that would be acceptable in an environment that requires intrinsically safe equipment. The electronics also need to be carefully current-limited so there's no chance they overheat and cause an explosion that way too. |
