I'm far from any expert but it appears that what you are trying to do is
make a solid-state switch.
There are two other ways to do this.
1. Use the RCX it's self as the switch. The RCX motor port in OFF mode would
be the switch closed and the motor port in FLOAT mode is the switch in open.
But I don't know if this is the best idea depending on what your planning to
run on it.
The safest method would be to use an optoisolator (I think it's called) It's
a package with a LED and a Phototransistor in one little package. You'd use
the RCX to 'light' it and it would do the same as your schematic but would
be electronically isolated. This also allows using two of them with reversed
polarity and you can have two switches on one port.
Your other option is a relay as that link I supplied showed.
Hope that's a little bit of help.

| (...) Thanks a lot, Dean! Total electrical isolation is a good idea to achieve what I'm planning to do. I am trying to switch circuits of various Voltages (a 12V circuit at the moment in the form of an IR beamer). Do you have any information on both (...) (22 years ago, 28-Aug-02, to lugnet.robotics)
