Matrix combination of elementary switches: general considerations and application to MEMS relays

This paper addresses some general aspects of switching devices consisting of a parallel-series (matrix) combination of elementary switches. The discussion is aimed at the derivation of criteria, which allow judging the potential of performance up-rating under rated current and interruption conditions. The elementary switch types considered are arcing switches and novel arc-free micro-switches. The latter are studied in some more detail in comparison with experimental data.
