Disclosed is a spring-type power failure restoration temperature control switch capable of controlling multiple load circuits. The temperature control switch comprises a metal shell, multiple connection terminals and a metal end cap fixed to the metal shell, a ceramic guide frame heating element arranged between the metal end cap and the metal shell, a ceramic push rod movably and penetratingly arranged on the ceramic guide frame heating element, a bimetallic strip in contact with the ceramic push rod, a movable spring provided with a movable contact, a static contact piece provided with a static contact and a lower contact. When the temperature of loads reaches a set value, the bimetallic strip is heated to kick, and the movable contact and the static contact are separated to open the circuits. The other side of the movable contact is connected with the lower contact in a closed manner, and the ceramic guide frame heating element is energized to emit heat so as to enable the bimetallic strip and the temperature control switch circuit to be kept under the disconnected state. The bimetallic strip can restore only by deenergization so as to enable the temperature control switch circuit to be closed, and the ceramic guide frame heating element circuit is opened.
