Most overtemp switches like that trigger at 135 to 150 Celsius.
Personally I would not want to have to take the iron out and then wait
for it to come up to operating temp.

Good used Weller irons with temp controlled tips can be bought at very
reasonable prices. Or do like I did, shop around- I bought just the
handle/cable assembly brand new for about $50 or $60. I put it in a
good ceramic iron holder I already had, and used a surplus 24V AC
transformer to power it. Get one rated at 2.5 to 3A.
