Abstract
A switch structure substantially reduces the effect of contact resistance by placing two mechanical switches in parallel between a source and a load, and sequentially closing and opening the mechanical switches so that one switch closes before the other switch, and opens after the other switch. The switch structure with the two mechanical switches can be realized with standard micro machined switches or as a micro-electromechanical system (MEMS) cantilever switch.
