The boiler 9 stands on a hinged flap 7 poised by a plunger 16 actuated by a counter-weighted lever 12. The lever 12 carries a three way mercury switch 18. When the boiler 9 is filled with water and the main switch operated by hand, the lever 12 is lifted against its weight 15 causing the mercury switch to make contact between the terminals 19, 19, in the heater circuit set for operation by the time switch in the clock 5 which closes the circuit at a given moment.; When the water boils, it is siphoned into the teapot 8 on the rigid platform 4. The boiler 9 loses weight and the weight 15 falls, causing the mercury switch 18 to make the contacts 19, 19 which breaks the heater circuit and completes a buzzer and lamp circuit.
