Why do some electrical appliances lack an on-off switch?

Since childhood, I've believed that it is unsafe to unplug an electrical appliance that is under load. More recently, I see this popular safety tip given on the net with the reasoning that unplugging an appliance under load can cause a spark.
At work I deal with 480 volt power cords, and it is considered a serious error to unplug a device like this while under load.
But two appliances come to mind that, as far as I know, never have on-off switches; electrical irons for clothes, and the George Foreman grill. I know there are now several models of George's grill, but I can attest that the one I own did not come with an on-off switch.
