Abstract

An electric immersion heater and integrated control (50) for an electric kettle or jug having a creep bimetal or trimetal (60) provided in good thermal contact with the head of the heater via a copper collar (68) disposed around the heater stud. The bimetal or trimetal acts upon a snap acting microswitch (94) which controls a set of contacts (100, 101) in series with the heater element. The microswitch (94) co-operates with a pivot point which is movable by means of a control knob (59) in order to vary the water temperature at which the contacts are opened. The microswitch is arrange to close the contacts when the water drops below that temperature and so the heater will cycle.
