Basically, No. For them to be on separate circuits, they could not be switched on one pole. If you could, they would be on the same circuit. If you joined the wires from both circuits in this way, you would circumvent the purpose of the circuit breaker, violate code, and create a fire hazard.
On the other hand, it could possibly be done using a couple relays but that is not a simple solution either.
Also, depending on what exactly you are doing, a sub-panel for both circuits could be installed off the main breaker and basically create two "sub" circuits. you would have to make sure they are rated correctly.
Please consult a Electrician with more detail about what you are trying to do before attempting anything.

If you could substitute the single pole switch for a double pole switch this would solve your problem. The throw of the switch would cause your two circuits to become energized.
Diverging circuits
yes we can use as a single phase circuit because at practise directly the 3-phase circuit is made by combining the three single phase circuits
All motor circuits require protection against single-phasing.
Check continuity
Three phase electricity is used instead of single phase for industrial situations. Industries use three phase electricity instead of single phase to operate electric motors driving heavy machinery. Three phase electrical motors produce more power from the same amount of electricity and maintain steadier speed. Small portable motors such as drills and mixers use single phase. Motors used around the house are single phase. Motors used to run large industrial machines use three phase.
If it is a single bulb, it is probably the bulb. Many tail light bulbs have two separate filaments, with the turn/brake being much brighter than the marker light. The tail light and turn/brake circuits are completely separate.
Yes, there is a difference between single phase and three phase circuits.
a circuit in which secondary coil alone is tuned
No, commutator motors as used in vaccum cleaners for example do not use a starting winding. Single-phase induction motors need a starting winding without which they will start in either direction if given an initial twist.
As many as you want without exceeding the 100amps. You could have 100 circuits if all you have is a single 100watt light on each circuit.
