How to make automatic DC and AC phase changer switch

How to make automatic DC and AC phase changer switch

In this project we learn how to make automatic DC and AC phase changer switch easy at home with the help of video and circuit diagram. this switch is specially design for auto switch change. for making this project we need some components.

How to make automatic DC and AC phase changer switch

Components: 

• 6V Relay (2)
• PCB Board
• Connector (3)
• Soldering Iron
• Soldering wire

Circuit diagram of automatic line changer switch:

Circuit diagram of automatic line changer switch

• Take 6 volt 2 relay.
• both relay 1st pin use for 1st input
• and both relay 2nd pin use for 2nd input.
• both relay 5th pin use for output.
• now connect 1st relay 3 number pin with 4 number pin of 2nd relay.
• and 1st relay 4 number pin connect 3 number pin of 2nd relay.
• Finally connect 6 volt power supply with 3 number pin of both relay. (this power supply use for operate the relay.)

we learn it more batter with watching video.

Video of automatic line or phase changer switch:

Basic purpose of automatic line changer switch.

when light goes then we need to on UPS, Generator, or Battery. and change all switches. but using this switch when light goes then its automatically connect with 2nd phase or line. 

in simple word when in 1st input has no power then relay automatically connect with 2nd input switch. and we can get output continually.
