EDIT: PVC insulation is usually rated to 105C, or a bit over boiling temperature. Silicone up to 150C, and teflon up to 200C. & Mouser offers wire with very-high strand counts, i.e. 24ga with 19 strands of 36ga. Most common, though, is 7 strands which is a bit stiffer.
Thanks for adding to the thread, Grinnin. I've used on/off switches also. As it may take 10 minutes or more to cycle from too hot to too cold if the switch is easy to operate, it works well.

Once you get the heat layer closer to the body the on/off time shortens quite a bit.
