the circuit that needs to be switched (I'll call it circuit "A")
It is in between two pins of a larger circuit, so the "negative" pin (following current flow from pos. to neg. ) , is *not* grounded -- it goes back into the circuit.
how can i use transistor in it to switch it on and off.
i cant find any circuit i which transisto as a switch does not use ground
