A bit off topic, but I'm sure this esteemed thread will have some answers. I'm having a debate with our engimneering group on what push buttons to use on a purged panel in a class 1 div 2 area. The purge I think is a Z purge (alarm only). I contend a stanadard pushbutton is OK, engineering says I have to use explosion proof. What say you?
