A two-speed temperature control power switch comprises a switch housing, a sensor housing, a pedestal, a bimetallic strip, a push rod, a moving contact and a fixed contact. A ladder stand is arranged under the inner cavity of the sensor housing and is used for placing the bimetallic strip. The bimetallic strip is a round strip and comprises an active metal layer and a passive metal layer. The active metal layer and the passive metal layer are tightly combined to be a two-layer structure. The upper surface of the active metal layer and the lower surface of the passive metal layer are cambered surfaces recessing from the active layer to the passive layer. The two-speed temperature control power switch helps to ensure that the bimetallic strip can deform rapidly, allows the deformation to be accurately transmitted to a switch contact, enables a contact connection circuit to be opened and closed, and enables an open circuit to be controlled.
