Abstract

The present invention discloses a power supply switching switch, belonging to the field of power supply circuit switches capable of maintaining long-term power supply of a power supply circuit and without outage. A storage battery binding post is fixed on an insulation housing, and a positive pole binding post and a negative pole binding post respectively penetrate internal and external surfaces of the insulation housing; a fixed mount is fixed at the inner housing of the insulation housing, an electromagnet is fixed on a seat rack of the fixed mount and is insulated from the fixed mount, an electric shock arm is fixed at the upper end of a vertical stand of the fixed mount through a rotating shaft, a tension spring is hung on the electric shock arm and the seat rack of the fixed mount, anupper contact is fixed on the storage battery binding post, a lower contact is fixed on the electric shock arm, and a magnet is fixed at one surface at the lower portion of the electric shock arm andcorresponds to the position of an iron core of the electromagnet. The power supply switching switch can charge the storage battery, can perform timely power supply after outage, is suitable for installation and usage of power supply circuits such as schools, mini-type factories and mines, office spaces and houses, and can continuously maintain electrifying of the power supply circuit after outage.

Description

technical field [0001] The invention relates to a conversion power supply switch for maintaining long-term power supply of lighting circuits without power failure. Background technique [0002] Today's power supply in my country is in short supply, and residents often stop power consumption, and even schools often have power outages. Therefore, many schools and families use batteries for backup. However, after a power outage, the circuit of the storage battery needs to be converted by a manual switch, causing the lighting to be interrupted for a period of time. To this end, we organized many school teachers to design an automatic switch that can automatically connect the circuit of the battery in case of power failure through long-term research and experiments. Contents of the invention [0003] The purpose of the present invention is to provide an automatic switch that can automatically connect the circuit of the storage battery in case of power failure. [0004] In or...
