I've not seen them for sale here... maybe it gets too hot?

biumetalic strip= heater ?

constacts NO or NC

there's a bunch of diffrerent ways they can use them

most I've seen had three pins but only used 2,

I saw one that used 3 pins and the case (it was in a Toyota light truck)
I think it had real electronics inside it (not merely a capacitor)
