Hello,
I want to make an electronic controlled bidirectional switch, similar to a push button switch in operation, it is to be controlled (to connect) with a pulse. I want it small and simple.
I thought about using two similar transistors and connect them in parallel but in reverse direction (C&E - E&C - B&B), or an NPN and it's complement PNP parallel but not reversed (I tried using 2n3904 and 2n3906). Whenever a pulse comes to the base, the transistors should be connecting in both directions. I also tried to use bc548, bc109 and bc337 with bc327.. they didn't worked properly.. Any idea what transistors I should use?? I'm not caring about the current through this switch.. 20mA is good.
I attached this picture for more clarification
Thanks,
Hazim
