    I am new to this forum, and a novice too... so please correct me if I am wrong.
    I want a single lighting switch(single way) at home which controls two sets of tube (~ 50W each) separately,

    Here's what the single switch does when flipped on-and-off quickly,
    On -> Light A turns on
    Off -> A turns off
    On -> Light B turns on
    Off -> B turns off
    On -> Light A and B turns on
    Off -> A & B turn off
    ...cycles repeat..

    In my house a Chandelier does this, but can't open and inspect this nor I have the brochure of this. It is working using relay circuit I guess. I hear sound when it switches.
    In our country the rating is like this (210V - 250V, 50-60Hz). Please help by giving a simple solution for this. If the product is available what should I tell to get that. Please guide me in this.

    Thanks in Advance.

    Didn’t understood, connecting a single switch to tube A and B in parallel will do that but if you want that in a sequence then you have to give us the state of A and B both while toggling the switch...for example

    On -> Light A turns on and Light B turns off
    Off -> A turns off and Light B turns on
    ...cycles repeat..

    If its the second case, then you could use a counter to make that sequence for lighting, as per me doing these with a microcontroller is the easiest way.

    Good Luck

    @debjit625 :
    Thanks for the reply.

    This is one complete Cycle

    On -> Light A ON, Light B OFF
    Off -> Light A OFF, Light B OFF

    On -> Light A OFF, Light B ON
    Off -> Light A OFF, Light B OFF

    On -> Light A ON, Light B ON
    Off -> Light A OFF, Light B OFF
    Cycle repeat...

    Is there any ready made circuit available in the market that can do this?
