technical field

The utility model relates to a switch, in particular to an electromagnetic switch which can be automatically disconnected when the power fails.

Background technique

After a general power outage, people will not or forget to turn off the switches of electric lights and other electrical appliances. Like this, after the next call, the electric lights and other electrical appliances will be automatically turned on no matter whether they are necessary or not, which will cause unnecessary waste.

Contents of the invention

In view of the problems existing in the above-mentioned background technology, the purpose of this utility model is to provide an electromagnetic switch that can be automatically disconnected when the power fails.

In order to achieve the above tasks, the utility model is realized by adopting the following technical solutions:

A switch that is automatically disconnected when a power failure occurs, comprising a bottom cover and a button, characterized in that a pillar is installed on the bottom cover, and the button is movably installed on the pillar; the surface of the button opposite to the bottom cover A spring, a conducting post and an iron sheet are installed, the spring is located at one end of the button, the iron sheet is located at the other end of the key, the conducting post is located between the post and the iron sheet; the spring is connected to the bottom cover, The bottom cover is equipped with an electromagnet with a conductive winding wound on it, a power supply column and an electromagnet column, the electromagnet is located under the iron sheet, and the power supply column and the electromagnet column are located Below the post, the electromagnet post is connected with the conductive winding.

The iron sheet and the electromagnet are wrapped with insulating materials.

The switch of the utility model can be automatically disconnected in case of a sudden power failure under the premise of satisfying daily normal use, so as to save electricity and protect electric appliances.

Description of drawings

Fig. 1 is a structural representation of the utility model.

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Detailed ways

As shown in Fig. 1, the switch of the present utility model that is automatically disconnected during a power failure includes a bottom cover 9 and a button 1, and is characterized in that a pillar 7 is installed on the bottom cover 9, and the button 1 is movably installed on the pillar 7; the surface of the button 1 opposite to the bottom cover 9 is equipped with a spring 8, a conduction column 2 and an iron sheet 5, the spring 8 is located at one end of the button 1, and the iron sheet 5 is located at the other end of the button 1 At one end, the conduction column 2 is located between the pillar 7 and the iron sheet 5; the spring 8 is connected to the bottom cover 9, and the bottom cover 9 is equipped with an electromagnet 6 wound with a conductive winding on it, connected to a power supply The post 3 and the electromagnet post 4, the electromagnet 6 is located under the iron sheet 5, the power supply post 3 and the electromagnet post 4 are located under the conduction post 2, and the electromagnet post 4 is connected to the conductive post 4. winding connection. The iron sheet 5 and the electromagnet 6 are wrapped with insulating material.

When in use, the power supply column 3 in the switch is connected to the power supply, and the conductive winding is connected to the electrical appliance. When the button 1 is pressed, the conduction column 2 contacts the power supply column 3 and the electromagnet column 4 at the same time, When there is current, the electromagnet 6 generates a magnetic force to attract the iron sheet 5. This magnetic force ensures that the button 1 will not be disconnected due to the elastic force of the spring 8, and the electrical appliances connected to the conductive winding can obtain the working current at the same time; when the power is off, the conductive winding No current passes through the middle, the magnetism of the electromagnet 6 disappears, and the suction force on the iron sheet 5 disappears accordingly, the button 1 automatically takes off under the action of the spring 8, the conduction column 2 is disconnected from the power supply column 3 and the electromagnet column 4, In this way, when the circuit receives electricity, the whole circuit is still in the disconnected state, so as to achieve the purpose of saving electricity and protecting electrical appliances.
