    Hi all,

    I have been making some little side light for the kids. It's very simple with each using a 12vdc power supply to 12vdc 2.1mm socket, socket to switch, switch to 48SMD LED 12v panels.

    The first 3 lights were perfect using a nice little switch like this one http://www.ebay.co.uk/itm/5-x-Blue-LED-On-Off-Round-Rocker-Switch-Lighted-Car-Dashboard-Dash-12V-/261459896191?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item3ce039677f

    The last one used a switch like this http://www.ebay.co.uk/itm/Angel-Eye...mponents_Supplies_ET&var=&hash=item3ce344281b and the LED panel is very dim and doesn't really light anything up. Is the switch stealing power from the LED panel?

    Regards
    Nick

    Both switches require power for their indication. However, from the item description, its not possible to determine how much power they require. All I can say is that it entirely possible that the new switches are "stealing" too much power. Where are these side lights for the kids going to be installed?

    I'll get a switch like the first ones to replace it then. They are going in their play room, they MAY want them in their bedrooms though. Is there anything else I should do for safety if that's the case?

    Nick, are you sure you've wired up the switches correctly, Sir?

    I suspect you have basically wired your load in series with the indicator LED. Did you wire your battery to the pins marked "power negative" and "power positive", and your LED board to the pin(s) marked "load positive" and to the battery negative?

    The other ones absolutely :), this one not so sure :confused: hence the questions. Reading Bobtph's post may I have wired it in series. I shall go and try it properly and report back.

    Thanks everyone.
