Hi,
I understand that NC pin has no internal connection, so it can be tied to GND. Is my understanding correct?
Best Regards,

Satoshi-san,
Signal switches terminals have the abbreviations NC, NO, and COM. The abbreviations identify the type of terminal on the signal path
NC = Normally Closed
NO= Normally Open
COM = Common
The letters "NC" for signal switches reference Normally Closed instead of "Not Connect". You may tie the Normally Closed signal path to ground if you would like to use the 2:1 switch in a 1:1 configuration.
Thank you,
Adam
Satoshi-san,
I'm sorry I miss understood your question. Yes, you may connect A2 to ground or leave it floating because it is not internally connected.
Thank you,
Adam
