An electrical apparatus includes a housing, a shielding plate, a first elastic element, and a second elastic element. In this case, the housing has at least one heat dissipation opening. The shielding plate has at least one first hole, a first sidewall and a second sidewall. The shielding plate is disposed parallel to at least one part of the housing. When the shielding plate is moved, the first hole and the heat dissipation opening are aligned. At least one part of the first elastic element contacts the first sidewall. The first elastic element is made of a shape memory alloy. At least one part of the second elastic element contacts the second sidewall. The shielding plate is movable between the first elastic element and the second elastic element.
