Summary:Thermal Switches In article number 2213371, Damiano Pasini, and co‐workers leverage thermally induced contact to introduce a mechanical metamaterial that can undergo reversible snap‐through instability and can operate entirely through temperature actuation, hence eliminating the need for any mechanical intervention. The functional reversibility is showcased for the development of a novel thermal switch with an OFF‐ON‐OFF function, and the temporal morphing of deployable structures suitable for space solar arrays and soft robots.
