Abstract
Three-way power change-over switch, it is related to the field of essential electronic element, including housing, power supply all the way and two road power supplys is installed on housing, three-way power is also installed on the housing.The present invention designs more than, realizes and automatically switches between three-way power, automatic identification primary and secondary priority, and has machinery and electric interlock between three-way power, securely and reliably, easy-to-connect, easily with operation.The present invention adds one group of power supply, the so operation for those important events You Ji roads electric power incoming line on the basis of original two-way power supply, and control and security performance have and big guarantee.
Description
Technical field
The present invention relates to the structure in the field of essential electronic element, more particularly to change-over switch.
Background technology
Existing product can only realize the conversion between two-way power supply, and many important events now can not power off, the tunnels of Dou You tri-
Electric power incoming line, cause wiring, troublesome in poeration.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, there is provided three-way power change-over switch.
The object of the present invention is achieved like this：Three-way power change-over switch, including housing, installed on housing electric all the way
The road power supplys of Yuan He bis-, also install three-way power on the housing.
The present invention designs more than, realizes and automatically switches between three-way power, automatic identification primary and secondary priority, Er Qiesan
Have between the power supply of road machinery and electric interlock, securely and reliably, easy-to-connect, easily with operation.
The present invention adds one group of power supply on the basis of original two-way power supply, so for those important events You Ji roads
The operation of electric power incoming line, control and security performance have and big guarantee.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
As shown in figure 1, three-way power change-over switch, including housing 4, power supply 1, two road power supplys 2 all the way are installed on housing 4
With three-way power 3.
Claims (1)
