Hello,
is there an ON/OFF or Short/Open momentary switch working by AC power? which means short/open is controlled by AC on/off.
i am testing a simple LED sync with music circuit
and its powered by 9V DC adapter, and i plug the adapter in the power strip.
a problem that i have now is .. when i turn off the power, LED is still blinking by remained power in adapter.
so, i am trying to figure out the way to cut the actual power flow between the circuit and power adapter in order to make LED stop blinking immediately when power strip is turned off.
what i am thinking is.. i keep feeding the circuit with 9V, and just cut the current flow (or whatever proper term) with something that i am looking for above.
does it make a sense to you?
is there such thing off the shelf or should i create one?
thanks in advance.
