Can I create a network switch to which all nodes are connected in NS3?

Yes, but not with the "plain" ns-3. A new module has been proposed but it has not (yet) been reviewed.

Oh, forgot...
Do NOT bump your requests after 2 hours again.
We believe that patience is a virtue, and if we feel again that you're impatient, we'll teach you to be patient by not replying to your questions. I hope you'll get the subtle hint.

Dear Tommaso,
Thank you for your reply.First of all sorry for repeating the question,I thought of making a clarification about the my question.
I have a doubt regarding your reply.
Has that module developed or in the development stage?Where can I find out that module(in NS3 dev page)?
OR
Would it be possible for me to use BrigeNetdevice to realise ethernet switch?Because I have seen that you replied to one of the questions in the group as follows,
Bridge/Switch: it's implemented by the BridgeNetDevice. It works... like a bridge (and like a switch).

Hi,
The actual limitation could be in the csma (or point to point) net devices. We discussed this a lot and I'm sure you'll find the treads.
the Bridge module is mimicking a switch. It is auto-learning the MAC/port pairs and it is able to switch the packets in the right output port.
Eventual internal packet collisions are handled by the output NetDevices.
