摘要： Featured is a particulate and pressure redirection barrier for an electrical breaker as well as a breaker embodying such a barrier. Such a barrier includes first through fifth segments, where the first segment includes a first and second side section and a bottom section that are coupled to each other so as to form a generally U shaped structure. The second segment is coupled to the first side section so it extends outwardly at an angle from the first side section. The third segment is coupled to the second side section so as to extend outwardly and at an angle from the second side section. The fourth segment is coupled to the second segment so as to extend outwardly from and at an angle with respect to the second segment. The fifth segment is coupled to the third segment so as to extend outwardly from and at an angle with respect to the third segment. Such a configuration of the fourth and fifth segments is such that gas flowing along a surface of the second or third segments is redirected at an angle with respect to that surface.

摘要： Pilot switch circuitry coupled across first and second terminals of a microelectromechanical system (MEMS) switch is provided to reduce or eliminate arcing between a cantilever contact and a terminal contact when the MEMS switch is opened or closed. The pilot switch circuitry establishes a common potential at the first and second terminals prior to, and preferably until, the cantilever contact and terminal contact come into contact with one another when the MEMS switch is closed. The pilot switch circuitry may also establish a common potential at the first and second terminals prior to, and preferably after, the cantilever contact and terminal contact separate from one another when the MEMS switch is opened.
