The actuator may comprise a button thermostat or a variable thermostat arrangement.

Liquid heating vessel

A liquid heating vessel comprises a heater plate (2) for closing an opening in the base of the vessel and clamping means (6) separate from the heater plate (2), the clamping means (6) grippingly receiving and clamping together a lower portion (12) of the vessel wall (14) and a peripheral portion (4) of the heater plate(2).

Liquid heating vessels and controls and components therefor

A liquid heating vessel comprises main heating means 200 arranged to heat water in the vessel to boiling and thereafter to be automatically de-energized and secondary heating means 202 for maintaining water in the vessel at a temperature at or below boiling wherein the vessel comprises a single manually operable actuator 48,50;148,150 for energising said main heating means and also for de-energising said secondary heating means. The control employs leaf springs which comprise a root region 26 for mounting the spring and a narrower, free tip region 28, said spring having two stable curved positions such that it is moveable between said positions by application of a force to the concave face in the tip region or to the convex face in the root region.
