Installing toggle switch - help?

Recommended Posts

I'm trying to install a toggle switch (on/off) in my self built bullet mic, I've got a +/- toggle switch (two seperate switches but with one toggle, if that makes sense?) interrupting both the + and -.

I had the wires going straight from the mic capsule to the out jack.The mic works fine when all wires are connected, gives a nice clean sound.

However, I now have the switch in between, and it gives terrible buzz when I switch it off.

I've tried switching the + and -, but that doesn't change anything, still buzzes when off.

Any ideas? Help?

Try putting + and earth on the switch instead of +/-. The buzz is an earthing issue so disconnecting the earth should fix it. Be careful though, try it at low volumes first in case you get a pop.

I have 2 wires coming out of the capsule (black & red) so I dubbed them + and -.

I tried putting a single switch to disconnect only one of the wires (so that only one of the wires would be diconnected when off), however this gave the same result: buzz when off.

Sorry, I missed some vital points in your OP, like "self built" and "jack".

Are you using an unbalanced mic in a balanced jack input?

LOL.

It's an unbalanced mic, i.e. only a black & a red wire coming from the capsule. (Although strangely enough the mic it came from had the 3 pin OUT but going to a normal 1/4 jack.)

It's now going to a 1/4 jack out.

If anyone's interested, it's working as it should, I put a resistor at the unused pins of the switch. Dead quiet now.

Thanks again!

Here's the result: it looks pretty good and it sounds SWEET.
