With the growing interest in lunar missions during the last few years, the demand for technologies which allow survival through the extreme conditions of the lunar night has increased. One promising approach is to reduce heat losses during the night, while maintaining a good heat rejection capability during the day. During the development of such a device at Lunar Outpost EU (LOEU), it was noted that the main performance parameter is strongly dependent on the processing approach of the test results. To better understand the switches performance under different use-case scenarios, an extended definition of the turn down ratio (TDR) is being proposed by introducing a routed and an extracted TDR.
