Abstract
Switches, breakers that incorporate a phase change material are disclosed, as well as electrical devices including the same. A switch includes a first conductor, a second conductor spaced a distance from the first conductor such that the second conductor does not contact the first conductor, and a switching device electrically coupled to the first conductor, the switching device having a phase change material that, when heated, expands to electrically contact the second conductor.
