Abstract

A control assembly for a cordless liquid heating apparatus comprises a control (2) for mounting to the liquid heating apparatus to control the supply of electrical power thereto, a cordless base connector (4) adapted to supply electrical power to the control (2) when engaged therewith, and a switch arrangement for making or breaking an electrical circuit for supplying electrical power to the liquid heating apparatus. The switch arrangement comprising a fixed electrical contact (6,8) provided on the cordless base connector (4) and a moveable electrical contact (12, 16) for engagement with the fixed electrical contact (6,8). The moveable electrical contact (12, 16) is mounted at a free end of a resilient member (10, 14) that is fixed at one point and can be flexed to effect movement of the electrical contact (12, 16), the resilient member (10, 14) being constrained in its movement at another point between the fixed point and the free end so as to control the movement of the electrical contact (12, 16) that results from flexing of the resilient member (10, 14).
