Abstract

The utility model relates to a switch for disconnecting the power automatically when the power-off condition occurs first and then the power-on condition occurs later. The switch is composed of switch compressed spring sheets and an electromagnet. The switch is characterized in that a first compressed spring sheet (1) and a second compressed spring sheet (2) are connected in a circuit, two ends of the first compressed spring sheet (1) are connected with wires, one end of the second compressed spring sheet (2) is connected with a wire, the other end of the second compressed spring sheet (2) is connected with the electromagnet (3), and the second compressed spring sheet (2) is provided with a power-off automatic pop-up device (4). The switch of the utility model has the following advantages: when the power is in abnormal power-off conditions, the power can be cut off automatically, and then the power-off state remains when the power-on condition occurs later so as to prevent the damage of possible impulse currents on loads, and the normal power supply can be realized when the power supply is in normal conditions. The device can be widely used in apparatuses which are not suitable for being started automatically, such as various lighting apparatuses, instruments and meters, household appliances, etc., and advantages, such as simple structure, easy utilization, low cost, etc., can be realized.

Description

The switch of auto power off of sending a telegram here again has a power failure
(1) technical field
The utility model relates to power switch device, and the switch of auto power off of sending a telegram here again specifically has a power failure.
(2) background technology
At present commercially available key switch comes the control circuit break-make by manually pressing seesaw or wrench, and running into when having a power failure can not the self closing circuit, in the situation that can automatic recovery of power supply after having a power failure when unmanned on the scene, electrical equipment can be worked as usual.Result is in vain waste electric energy not only, sometimes also can lead to the accidents such as fire.
(3) utility model content
The purpose of this utility model is the weak point that is to overcome mains switch in the above-mentioned background technology, the switch that provides a kind of power failure to send a telegram here again auto power off.
The purpose of this utility model is achieved by the following measures: the switch of auto power off of sending a telegram here again has a power failure.This switch is by the switch making leaf spring, and electromagnet forms, and two making leaf springs are coupled to circuit, and the two ends of the first making leaf spring are connected with wire, and an end of the second making leaf spring connects wire, and the other end connects an electromagnet, and the second making leaf spring is with cutting off the power supply from bounce device.
The utility model has following advantage.When power supply is in the situation of undesired outage, can auto-breaking, more still keep off-position when sending a telegram here, to prevent possible impulse current to the damage of load, after confirming that power supply is normal, then realize normal power supply.This device is not suitable for automatically actuated equipment after can being widely used in power failure, various lighting apparatus, instrument and meter and household electrical appliance etc., have simple in structure, easy to use, low cost and other advantages.
(4) description of drawings
Accompanying drawing 1 is the schematic diagram of the utility model electrical connection one.
Accompanying drawing 2 is the schematic diagram of the utility model electrical connection two.
(5) embodiment
Concrete structure of the present utility model sees also accompanying drawing.Send a telegram here the again switch of auto power off of having a power failure is comprised of switch making leaf spring and electromagnet, it is characterized in that the first making leaf spring 1 and the second making leaf spring 2 are connected in circuit, the two ends of the first making leaf spring 1 are connected with wire, one end of the second making leaf spring 2 connects wire, the other end connects electromagnet 3, and described the second making leaf spring 2 is with cutting off the power supply from bounce device 4.
Send a telegram here the again switch of auto power off of having a power failure is applicable to 220 volts of alternating current circuits.When switch key when hold to " opening ", the first making leaf spring 1 be connected making leaf spring 2 and connect wires and connect circuit, electromagnet 3 is magnetic simultaneously, keeps being connected with the second making leaf spring 2 making the circuit connection.Run into power failure, electromagnet 3 loses magnetism, simultaneously under the effect of bounce device 4, button rebounded " pass " end, the first making leaf spring 1 and the second making leaf spring 2 and automatic shutdown circuitry, then when sending a telegram here, can't automatically connect because two making leaf springs still disconnect circuit with wire.

Claims (1)

1. the switch of auto power off of sending a telegram here again has a power failure, comprise the switch making leaf spring, electromagnet, it is characterized in that the first making leaf spring (1) and the second making leaf spring (2) are coupled to circuit, the two ends of the first making leaf spring (1) are connected with wire, one end of the second making leaf spring (2) connects wire, and the other end connects electromagnet (3), and described the second making leaf spring (2) is with cutting off the power supply from bounce device (4).
