As used in thermal switches. Instead of in form of a bimetal strip
and continuous curving with temperature, these are 0.5 inch diameter
and make a definite flip from concave to convex at a specific
temperature. About 1mm of abrupt movement gives a very positive
transition for the switch contacts. Would it be possible to change
the characteristic temperature by grinding back a spot/ring/radii?
on one face? which face? or would it just destroy the
action/activation force?
I belive "Clixon" in the UK make these.
That is 'Klixon', which was a division of Texas Instruments.
Now it's a division of Sensata

Thanks for the spelling correction and link. Its a lot of years since I
played about with them. They were very popular in water heater
circuits at one time.
They still are, but a lot of their thermal motor starters are
discontinued.
