Abstract
A kind of power-off protection switch of the present invention includes a housing, the magnetic member and more than one magnetic direction detection device. The magnetic member is movably disposed in the housing. The magnetic direction detection device is fixed and disposed in the housing to correspond to the magnetic device, and is connected with the power line of the electric appliance such that the magnetic direction detection device makes the power line of the electric appliance form an open circuit when the magnetic device moves relative to the magnetic direction detection device. Therefore, when the electric appliance shakes and tilts, the magnetic member moves relative to the magnetic direction inspection device such that the magnetic direction detection device makes the power line of the electric appliance form an open circuit, so as to protect the electric appliance.
