With how you have it, wouldn't you have to supply a -9v so it would switch between the +9v and -9v with just the one relay?? Sorry if this is elementary but my "little" brain only came up with what I had with the relays... LOL Can't seem to comprehend what you are describing... The top 3 voltages ( +V , +9 and -9) in your drawing above, are those the "supplied" voltages?? Dave ```
