A beverage warmer comprising electric-heater means having an electrically heated non-magnetic surface, an energizing electrical circuit for said means having a magnetically operable normally open switch mounted adjacent said surface in a predetermined location, and a non-magnetic beverage container

A beverage warmer comprising electric-heater means having an electrically heated non-magnetic surface, an energizing electrical circuit for said means having a magnetically operable normally open switch mounted adjacent said surface in a predetermined location, and a non-magnetic beverage container having a closed bottom with a periphery adapted for stabilized removable mounting on said surface, said container having thereon a magnet near one to the exclusion of another region of said periphery, said switch being locally responsive to said magnet to close for a mounted condition of said container when said container is oriented to place said one region in operative proximity to said switch, and said switch being sufficiently non-responsive to said magnet to thereby remain open when said container is oriented to place said other region in proximity to said switch.
