Just recently opened multi effect pedal using CD4011BM for every momentary switch.Is this chip the one used as switch or just controlling the switch? I don't see any other active component like FET.
Thanks

I have never seen that done and it's never occurred to me that they could be used like that -  but that doesn't mean anything!

If I saw that in a circuit I be scanning for other switch chips (or things that could be used as switches).

According to the water analogy of electricity, transistor leakage is caused by holes.

Sorry my info is lacking, i saw 2 CM053B chips. This might be the switches used for the four circuits.
