S4), contact switch movable contact is connected on changer lever 1；Changer lever 1 links with moving contact switch movable contact causes left-side switch group
Separating brake and right-side switch combination lock, or cause left-side switch combination lock and right-side switch component lock.
Wherein, left-side switch group is identical with the group number of the contact switch of right-side switch group.
Changer lever 1 is linked with moving contact switch movable contact so that the contact switch of left-side switch group is closed at, and left side is opened
Right-side switch group can not then be closed during the group closure of pass；Or, the contact switch of right-side switch group is closed at, right-side switch group
Left-side switch group can not then be closed during closure.
Contact switch supply terminals and load wiring end are respectively arranged with binding post.
The contact switch group of left-side switch group connects conventional power supply (1#, 2#), right-side switch by supply terminals respectively
The contact switch group of group connects stand-by power supply (3#, 4#) by supply terminals respectively；One contact of left-side switch group is opened
The load wiring end of pass group S1 and a contact switch group S4 of right-side switch group corresponding phase voltage is connected to after connecting respectively
One load R1, by another contact switch group S2 of left-side switch group and another contact switch group S3 of right-side switch group pair
The load wiring end of phase voltage is answered to be connected to another load R2 after connecting respectively, to connect conventional power supply or standby electricity accordingly
Source.
When conventional power supply 1# is different with conventional power supply 2# voltage, and conventional power supply 1# is identical with stand-by power supply 4# voltage
(such as 380V), and conventional power supply 2# (such as 660V) identical with stand-by power supply 3# voltage, it is possible to provide different voltages are loaded respectively
R1 and load R2 power simultaneously；When conventional power supply 1# is different with conventional power supply 2# voltage, and conventional power supply 1# and stand-by power supply
4# voltage is different, and conventional power supply 2# is different with stand-by power supply 3# voltage, by switching, can provide different electricity to load R1
Pressure, is provided without voltage to load R2.
