No, that's a mounting hole for putting a screw through to secure the switch to the table.

The gap is the space between the conductors.

Right?

No. They are binding posts for connecting your wires to the switch terminals.

The gaps are the spaces between the metal blocks. The gaps prevent current flowing from block to block unless a key plug is inserted to bridge the gap.

What are metal blocks in 2 way plug key?

Are my 33rd and 27th posts correct?

Yes.

In my practical we are told to connect these gaps ,how can we connect gaps?

See post #22.

Edit: Sorry, I meant post number 31.

The Wheatstone reference was due to the schematic symbol in question on the tiny, fuzzy image reminding me of a typical Wheatstone bridge setup.

I now realize that it's meant to represent a switching arrangement comprised of your Plug Key Switches (PKS's). So forget the Wheatstone.

Apparently you're meant to use the provided PKS's in the wiring up of your lab circuit. You'll have to figure out the wiring arrangement that makes the plug key switches accomplish the required reversal of the polarity of one of the cells.

Is this answer of my 36th post?

Your 36th post asked how to connect the gaps. That's easy: insert a plug key into the gap.

My previous response was to your question:
