<p>A hazardous apparatus, for example a microwave oven, includes a safety mechanism (210, 220, 240, 250) which automatically cuts off a supply of electric power when a panel (50) of its housing has been removed, even if the power supply cord (100) is still plugged in. The safety mechanism includes a switch (210) for cutting off the power. A cover (220) for the switch (210) is movable between a first position covering the switch, and a second position exposing the switch. The switch is biased to a power-cut-off position and the cover is biased to the first position. A structure (240, 250) on the panel is arranged to automatically move the cover to its second position, as well as to move the switch to a power-supply position, in response to the panel being in an assembled state. When the panel is removed, the switch automatically cuts off the electric power, and the cover moves to the first position covering the switch. <IMAGE></p> |
