I plug my iron into a toggle switch that is plugged into an extension cord. The toggle switch sits at the end of my ironing board and I can toggle it on and off during my sewing. When I am finished for the day, I unplug it at the toggle switch. With this device I don't have to leave my iron on the entire time that I sew, and when I am finished I don't have to bend over to the outlet.
One picture shows my plug and switch. The other shows the plug up close. I found it at a home improvement store.
