Fig. 1 is a kind of structural schematic diagram of switchgear of the utility model embodiment, as shown in Figure 1, the switchgear May include:

Single firewire switch 101 and for when determining that the state of single firewire switch 101 changes, change firewire L's The electronic switch 102 of on off operating mode；Wherein,

The electronic switch 102 is separately connected single firewire switch 101 and electrical equipment 103, the electricity by firewire L Sub switch 102 connects between zero curve N and firewire L.

Here, single firewire switch 101 is located on firewire L, for the switch for controlling firewire L on-off, single firewire switch 101 The switch that can be directly controlled for user, that is to say, that user can be directly changed the state of single firewire switch 101；Electronic cutting 102 are closed between single firewire switch 101 and electrical equipment 103；Electronic switch 102 is zero firewire switch, and zero firewire switch is Refer to while accessing the switch of zero curve N and firewire L, zero firewire switch can take electricity by zero curve N and firewire L, it can pass through zero Live wire power getting mode carries out taking electricity；Electrical equipment 103 between zero curve N and firewire L, can by zero live wire power getting mode into Row takes electricity.

The state of single firewire switch 101 can be divided into on-state and off-state, when single firewire switch 101 is connected, Electric current on firewire L can flow to electronic switch 102 by single firewire switch 101, due to electronic switch 102 connect zero curve N with Between firewire L, electronic switch 102 can carry out taking electricity using zero live wire power getting mode；In this way, the electronic cutting in switchgear It closes 102 and uses zero live wire power getting mode rather than single live wire power getting mode, enough electric energy can be provided for electronic switch, no longer needed External power supply mode is used, it can be to avoid since single firewire intelligent switch be using single live wire power getting and the problem of bring.

When single firewire switch 101 disconnects, electronic switch is flow to since the electric current on firewire L cannot pass through single firewire switch 102, electronic switch 102 cannot carry out taking electricity by zero live wire power getting mode.

When actual implementation, electronic switch 102 may determine that whether the state of single firewire switch 101 changes, in determination When the state of single firewire switch 101 changes, change the on off operating mode of firewire L, and then the switch to electrical equipment 103 may be implemented Operation, it can be powered for electrical equipment 103, or stop being powered electrical equipment 103；Specifically, in electronics When switch 102 controls firewire L connection, if can control when electronic switch 102 determines that the state of single firewire switch 101 changes Firewire L is disconnected, and then realizes that the stopping to electrical equipment 103 is powered；When electronic switch 102 controls firewire L and disconnects, if electric When sub switch 102 determines that the state of single firewire switch 101 changes, firewire L connection can control, and then realize to electrical equipment 103 power supply.
