The invention discloses the household power switch of electric leakage and electric shock prevention. The switch comprises a switch button, an outer frame, an installation plate and a rear seat. The switch button is located in the middle portion of the outer frame. The right side of the outer frame is provided with an installation plate. The rear seat and the installation plate are fixedly connected. The switch button and the rear seat are rotatably connected. The side surface of the rear seat is provided with a positive terminal and a negative terminal. A lead is arranged in the rear seat. The lead is fixedly connected to the positive terminal and the negative terminal. The middle portion of the rear seat is provided with a connection sheet. The left side of the connection sheet is provided with a rotation shaft. The surface of the rotation shaft is provided with an arc embossment. The right side of the connection sheet is provided with a telescoping rod. In the invention, a memory alloy is used to make a spring; during electric leakage, a heating resistor generates a high temperature so that the spring is contracted and losses elasticity; after a circuit becomes normal, the spring is cooled and is recovered to an original state; and electric leakage and electric shock accidents can be effectively prevented, the switch can be repeatedly used, and the service life of the switchis prolonged.
Description
technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a household power switch for preventing electric leakage and electric shock. Background technique [0002] A switch is an electronic component that can open a circuit, interrupt the current, or allow the current to flow to other circuits. In household use, improper use will cause the switch to leak electricity, which may easily cause electric shock to family members during use, resulting in accidents. Contents of the invention [0003] The purpose of the present invention is to provide a household power switch that prevents electric leakage and electric shock, which solves the problems raised in the background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a household power switch that prevents electric leakage and electric shock, including a switch button, an outer frame, a mounting plat...
