Hi.
Trying to locate a 12V simple sensor/thermostat/thermoswitch that will flip contacts as 'it is hotter than setting' and 'it is colder than setting'.
With tripping temperature adjuster; 0C to 50C OK
What would you suggest ?

These have a single contact relay :

Or just replace its relay with A SPDT ¿?

 

A SPDT relay will not have tracks on the PCB. Just use the existing relay contact to operate a new DT relay.

 

Thanks. Of course will not have the corresponding tracks/pin; bringing extra wire out.

 

Found This on Amazon. Have no idea if it is what you're looking for but it has three terminals. One might suspect it's a DT thermally activated switch. Found in the automotive section of Amazon, this may lead you to finding something closer to what you're looking for.
