ELECTRICAL SWITCH

An electrical switch is disclosed for switching an electric current between a feed and an outgoer. The electrical switch can be mounted in a switchgear assembly and as a result electrical contact can be made with the electrical switch by a feed and an outgoer of the switchgear assembly. In one embodiment, the electrical switch includes an internal voltage tap for supplying power to a switch-internal electronics system and a changeover switch. The changeover switch adjusts the electrical connection between the feed or the outgoer and the internal voltage tap. 本发明公开了种用于切换在馈入端和输出端的电流的电开关，其中电开关能够安装在开关设备中并且由此能够与开关设备的馈入端和输出端电接触。电开关包括用于向开关内部的电子器件供电的内部电压抽头和换接开关，其中换接开关在馈入端或输出端与内部电压抽头之间建立电连接。
