This is going to sound stupid but can I use an on/off volume control switch from an old small transister radio as a plain on/off switch? I want to shut off a 9 volt battery on a microphone when it is not in use, the switch has three tabs for wire connections, if it can be used this way how would I wire it, I just want to put it between battery and microphone on the battery wires its a new switch I have lying around just thought I could put it to use. Thanks in advance Joe K.
