I'm trying to understand just how an electric blanket heat controller works. Any insight would be helpfull.
The one I have is soley a mechanical device. A set screw determins the ability of a contact is made or broken. So how does it work? Is is based on the thermal properties of the metal used? Does it detect current flow?
All I know is that they have so much slop in the temperature of the blanket.
You turn it till the heat comes on and it gets too hot, so you turn it till the heat goes off and it gets too cold. So somewhere between the contact being turned on or off is the temperature I would be interested in and seems to be a big guessing game!
enlighten me please.
Thanks
