Description

The present invention takes up the field of electrical energy, and specifically, is a power strip that can be switched.

A power strip is an electric appliance for supplying power to a plurality of electric appliances at a place away from an outlet installed on a wall or the like. Power strips are widely used in everyday life because they can be connected to multiple plugs and are easy to operate. Most conventional power strips occupy space because the three-pole and two-pole outlets are arranged in parallel or alternately and the arrangement method is single, and the cord length is limited and can be used. Due to the narrow range and the lack of protective devices on the pushbuttons, if the user accidentally presses the pushbuttons, the electrical equipment will be temporarily shut off, which will have an adverse effect.
