Abstract

En anordning for innkopling i en elektrisk krets, hvilken anordning om- fatter (1) to FET-transistorer som er seriekoplet i en ledning i kretsen med sine kilder sammenkoplet eller med sine sluk sammenkoplet, og hvis tilstander kan endres ved hjelp av en spenning som virker på deres porter, og (2) en styr- ing som er koplet til porten i minst en av FET-transistorene, idet styringen reagerer på en overstrøm på ledningen og derved endrer tilstandene til minst en av FET-transistorene.An apparatus for connecting to an electrical circuit, comprising: (1) two FET transistors which are connected in series in a line of the circuit with their sources interconnected or with their outlets interconnected, and whose states can be changed by a voltage which (2) a control coupled to the port of at least one of the FET transistors, the control responding to an overcurrent on the wire, thereby changing the states of at least one of the FET transistors.
