The items in the image are electric kettle thermostat switches, often used for repair and replacement.
Function: These switches control the kettle's operation by automatically turning it on or off based on the water temperature.
Specifications: They typically operate at 250V and are rated for currents around 13A.
Material: They are constructed from plastic and copper components.
Features: These components often feature bimetallic strips that deform with heat to trigger the switch, ensuring safety by cutting power when the kettle boils.
