Abstract
A current control device is disclosed. The current control device includes control circuitry and a current path integrally arranged with the control circuitry. The current path includes a set of conduction interfaces and a micro electromechanical system (MEMS) switch disposed between the set of conduction interfaces. The set of conduction interfaces have geometry of a defined fuse terminal geometry and include a first interface disposed at one end of the current path and a second interface disposed at an opposite end of the current path. The MEMS switch is responsive to the control circuitry to facilitate the interruption of an electrical current passing through the current path.
