Hi,
I'm trying to build a circuit with two key switches, where both key switches need to be closed for the current to go through. I am trying to use a transistor so that one key switch feeds the collector, and the other feeds the base so that both need to be on to allow current to go through the emitter. I've tried this also with a MOSFET gate-drain-source and well as a general purpose transistor with no luck. I've seen similar tutorials on youtube where a guy is using a transistor to turn a bulb on and off by touching the base to the same source as the collector with the addition of a resistor. The image is my circuit. If there are things missing in the diagram it's because i don't know that they should be there. the resistor is brown, black, black, gold which according to the web means 100k-ohms +- 5%. Can someone please show me the correct circuit? Thanks.
