Abstract
A first structure has alternating fingers of first and second materials, the first material having a higher thermal conductivity than the second material, a second structure has alternating fingers of third and fourth materials, positioned to selectively contact the first structure, and an actuator connected to move the second structure. A method of manufacturing a heat switch includes forming a first structure in a first material having finger separated from each other by gaps, forming a second structure in the first material having fingers at least partially separated from each other by gaps, positioning the first and second structure adjacent to and in contact with each other, and connecting the second structure to an actuator. A method of operating includes receiving an activation signal at an actuator, and using the actuator to move one structure relative to another structure to change alignment between two regions of different thermal conductivity.
