Hi Ante, it's my fault for misunderstanding AC/DC: There really isn't a DC jack on the device. The box plugs into an AC outlet, and then a lamp or other device plugs into the port that I have been (incorrectly) calling a DC jack. Really, it's just a pass-through jack that supplies AC power from the wall to the device that's plugged into the jack when the relay is activated. ~Adam

Hi again, Yes, the DC jack is to be to power the unit from the wall. The 12v battery in the radioshack link is to power the RF remote that signals the unit to turn the relay on/off. Any ideas? Thanks Ante! ~Adam

Hi everybody, Thanks for the thought you've put into this. There is no battery in the unit. I just want to be able to power it using a battery. The RF *and* relay circuits come off of the tracks coming from the prongs going into a DC wall socket. Does this help? Thanks!!! ~Adam

Thanks for your reply! I tried hooking up a 9v to the prongs that would usually go into a dc socket to no avail. I was wondering, though, if I connected the battery at a different point on the board if I could get it to work. I have a feeling there is some stepping down of the power before it gets to the RF circuit which is what I need to activate with the remote. If I could find the point on the board after this stepping down has occurred, I could connect the power there. Do you think this would work? Thanks! ~Adam

Hi Ante! Thanks for the welcome. I realized what the electromagnet was after doing some research last night....haha...I guess I never understood that auto relays looked like that on the inside. You're right, the black thing on the side is a DC jack. I was hoping to not have to plug the unit into a wall to get it to work. Rather, I wanted to attach a 9v battery to power the unit. The relay has 24v written on the side, so I'm assuming that 9v might not be enough to power it? Do you think buying a 5 volt relay from Radioshack and soldering it into the board would work? Thanks again for the welcome and for helping me out on this! ~Adam

Hi Everybody, I hope this is the right forum to place this question. I just bought a Remote RF Light Switch from Radioshack. It has a little remote that you can use to turn a lamp that is plugged into the receiver block on or off. The receiver plugs directly into an outlet, and then the lamp plugs into the receiver. Basically, when the remote's "on" button is pressed, the circuit is completed by the receiver box and the light turns on. You can see the unit here: http://www.radioshack.com/product/index.jsp?productId=2103886&cp=&origkw=light+switch&kw=light+switch&parentPage=search What I would like to do is just use the circuitry inside the box as a remote on/off switch. I don't need it to turn anything on. I just want the thing to complete a circuit when I use the remote. Here's how the reciever works. There is a little electromagnet that, when activated, pulls a metal tab against a terminal to complete the circuit. Voila! The circuit is completed. Obviously, this unit needs power to operate the electromagnet, and I really don't want to plug the thing into a wall outlet (which is where it usually draws power from). Is there a way I can power the unit with a 9-volt battery? Here are some pictures of the circuitry: Thanks for reading this! If you can figure this out, I'll forever be in debt! Thanks again! ~Adam
