Description

A power-off self-breaking switch

technical field

The utility model relates to the field of household appliances, in particular to a power-off self-breaking switch.

Background technique

Now common ordinary switches need to be manually operated to turn on and off the power, which does not affect the use under normal circumstances, but in the case of frequent power outages, such as the university dormitory adopts a unified power outage method, people often forget to turn off the switch after power outages switch on so that the appliance will automatically start working after the power supply is restored. This is not only a waste of power resources, but also a huge safety hazard when people are not around.

Utility model content

The utility model provides a power-off self-break switch, which solves the problem that people forget to turn off the switch after the power is cut off, so that the electrical appliance starts to work automatically after the power is re-powered.

The technical scheme of the utility model is: a power-off self-break switch, including the upper part of the switch, the bottom of the switch, two energized wires, and the switch support arranged between the upper part of the switch and the bottom of the switch. One side of the switch support is equipped with elastic Components, on the outside of the elastic part, the upper part of the switch is provided with an upper conductive column and an armature, and the bottom of the switch is provided with a lower conductive column and a solenoid coil corresponding to the upper conductive column and the armature, and the two energized wires , one is connected to the upper conductive column, the other is connected to the inlet end of the solenoid coil, and the outlet terminal of the solenoid coil is connected to the lower conductive column.

Preferably, the upper conductive column and the lower conductive column can be contacted under the condition of electrification.

Preferably, the length of the armature is shorter than the length of the upper conductive post.

Preferably, the elastic component is a spring.

The beneficial effect of the utility model is: a power-off self-break switch, when the switch is pressed, the solenoid coil is energized, and the armature is sucked, and when the lights are turned off uniformly, the switch has no power, and the solenoid coil has no power. , under the action of the spring, the switch is bounced open, so that the switch is in the off state after the power is on, and the light will not be turned on, which will not cause waste of resources.

Detailed ways

A power-off self-break switch, including a switch upper part 1, a switch bottom 2, two energized wires, a switch support 3 arranged between the switch upper part 1 and the switch bottom 2, and an elastic part 4 is installed on one side of the switch support 3 On the outer side of the elastic member 4, the upper part 1 of the switch is provided with an upper conductive column 5 and an armature 6, and the bottom 2 of the switch is provided with a lower conductive column 7 and a solenoid coil 8 corresponding to the upper conductive column 5 and the armature 6 respectively. , the two energized wires, one is connected to the upper conductive column, the other is connected to the incoming line end of the solenoid coil 8, and the outlet terminal of the solenoid coil 8 is connected to the lower conductive column 7.

The upper conductive column 5 and the lower conductive column 7 can be contacted under the condition of electrification.

The length of the armature 6 is less than the length of the upper conductive column 5 .

The elastic member 4 is a spring.

When the electrical appliance needs to be used for normal power supply, the switch is manually pressed, and the upper conductive column 5 and the lower conductive column 7 are in contact at this time, and the circuit is connected. Conductive posts will not break.

When powered off, the current is zero. At this moment, the solenoid coil 8 is no longer attractive, that is, the armature 6 can no longer be attracted. Then the switch will bounce off under the action of the spring, so that the upper conductive column 5 and the lower conductive column 7 are separated.

When power is supplied again, since the upper conductive column 5 and the lower conductive column 7 have been separated before, the circuit will not be automatically connected, and needs to be manually connected.
