摘要

A cordless water boiling vessel (2) includes a stainless steel container to the bottom of which is attached an aluminium ring (6) incorporating a coiled electrical heating element (8) and steam control channel. The control sub-assembly (16) is integrated with a cordless electrical connector (18) with pressed steel carrier plate (22) and snap acting bi-metallic actuators (12,14) with similar operating characteristics to act at 120 deg. Celsius. The actuators control sets of electrical contacts with pivots (38) on upstands (42) on the carrier plate.
