US Patent 7522405 High current electrical switch and method

A method and system are disclosed for a high current electrical switch. The switch may be suitable for switching, rectifying or blocking direct current in the range of one to a thousand amperes per module or assembly. It does so with such high efficiency that it produces relatively insignificant heat; such that it requires little or no cooling by convection or radiation. The relatively low heat that is generated in the process is conducted away quite effectively by the electric cables connected to the device.
