High side switch question

[neo]

I tried the pnp high side and found this circuit to work well. Yes, that really is a germanium.

Yes, that should work fine in real life too.

The only issue might be speed, with such high value resistors, otherwise it's a good idea.

By the way, why did you decide on a germanium transistor? Is it just because it's cool to use old parts?

Its germanium because it was handy. Its for a 1 hertz signal, i physically built it and it worked well.

Schematics?

Plenty of schematics have been attached to the posts. You'll need to be logged in to the forum to see them. If you are having problems viewing them, check your firewall settings.

Here's another option which only uses one NPN transistor.
