Hi team,

When control pin is floating, is A and B connected or disconnected? Is there internal pull up or pull down inside of C pin?

When the pin is floating, it might be read as low, or high, or oscillating.

Hi Nison,

There is no internal pull up or pull down on the Control pin. In low frequency applications, you would likely encounter the Control pin reading Low, so the switch would be off. It is best practice though to tie the pin to a known voltage to ensure the state of the switch though.

Regards,

Alex
