Tactile switch image from KICAD. Any idea what is attached to what?

Hello,
Unsure what is connected to what from this design. Is one and two always connected or only when button is pushed.
Thank you in advance!!
Its for a MOM-normally open tactile switch (push button). Four prong. Best one I could find on Github/kicad library.

That is a DPST switch. When the button is up, nothing is connected to anything. When the button is down, 1 is connected to 2 and 3 is connected fo 4.

If you are using a typical SPST switch, that is not the right symbol. The common ones are SPST and have 1 and 3 connected together internally, and same for 2 and 4. When pushed, all four pins are connected together.

I'm assuming this is related to your question on the P.B. switch that has a internal connection between 1 & 3 and 2 & 4 which is essentially a SPST switch, but you would use the one you show for the benefit of the PCCT footprint/ layout.
What you could do is modify the symbol in the part editor to include the connections I mentioned and save it to the Switch library just with a different ID name.
