   Ah, my bad memory.  The problem was it couldn't switch the heating on.  As the   
   room cooled, the contacts tried to close, and just as they were closing there   
   was an arc and it caused the strip to warm up and bend away again.  It would   
   be intermittent at    
   first, then as the room got even colder it became continuous.

   The switch?  The thermostat is the switch.
