I seem to remember that being said in another post somewhere. I have a DPDT switch wired (Manual-OFF-Auto). The manual side receives it power right from the dist-block, and the Auto receives a power feed from the SSR. However, if the switch is in Auto mode but I don't have the relay turned on my voltmeter is still showing about 3VAC. I wired a small LED off the middle terminals of the switch so that when power goes to the outlet the light turns on. This works perfectly in Manual mode but the light also comes on during Auto mode even though the SSR is not switched on.
