So I had this idea to build my own mute switch into my rig. Should be simple really. I bought a light switch (the standard light switch you'd see at any light in your house etc). It has two screws which are the electrical terminals. I took an old 1/4" cable cut it in half. I am using a cd player and an amplifier to test this because I know I am getting constant signal. I tested with a regular 1/4" cable with an 1/8 adapter and I know that it works. Back to the switch. The lead wire goes into the terminal screw (or whatever they are called) and the 1/4 plug goes into amplifier. Same with the other screw / terminal. Plug the 1/4 (using the adapter) into the cd player and the cut wire gets clamped down in the screw/terminal. So I turn it on and all I get is a loud constant humming/buzz. When I flip the switch is goes off. I also tried the same thing with a toggle switch I had lying around instead of the light switch and I got the exact same results. What am I doing wrong? Sounds to me like a ground problem. But I am not sure, and if it is, how do I fix it?
