    Hello Ladies and gents.

    I don't mean to be a bother but I was directed here by Techdaddy as a possible source of an answer for a question.

    I have a Iwaki RD-30, and am using the Meanwell 24-150 PSU/converter to juice the beast of a pump.

    I would like to add a power switch. I am just not sure where to put it, or exactly how to wire the switch into the circuit.

    A suggestion or solution would greatly be appreciated.

    Also I was thinking of using the switch off an older PSU that I canibalised for extra parts.

    Below is a rough diagram and if someone is willing to edit it to provide an example I would appreciate it.

    do you want the switch to be inbetween the pump and the psu or the psu and the wall?

    You are going to want a switch that will shut off power to the PSU all together.
    You need to have a DPST switch between the two live leads from the wall.

    If you have a computer PSU, then you also need to either jump the green wire to any black wire on the atx connector, or add a switch there.
    The only difference there is that you can switch the pump off and leave the psu still plugged in with juice. (redundant)

    So your saying a switch beween the wall and the Meanwell, and just wire the pump directly to the Meanwell?

    I am not sure what you mean about running the ground to the Comp PSU (Enermax Noisetaker).

    As far as I understand the 2 PSUs would be totally independent.

    I have the DPST Rocker switch from the older PSU.

    Well the plan, for the most part is to leave the pump running unless I ABSOLUTELY need to turn it off, because the RD-30 can be tempermental about being turned on and off alot.

    The Mean Well is his pump's PSU, the computer's ATX PSU would be independent. No green-black jumpering involved.

    but my question still stands as to where to put the switch, and which wires to attach the switch to.

    do I put it between the wall and the Meanwell or between the Meanwell and the Pump?

    The switch I want to use is a DPST from an older PSU. I am aware tha if the swith can not handle the juice from the wall to the Meanwell that it could burn up, obviously bad. So.......would the logical choice be to put it between the Meanwell and Pump?

    Put the switch between the wall and the Meanwell PSU.

    I assumed that he was using a 2nd ATX PSU to power the pump, and jumpering would be required for that, at least as far as i know.

    Phelen: Since you dont want to shut off the pump often, why bother with a switch, if you need to operate, unplug it, as that would be about as intensive as adding a switch that you would have to reach around the computer to use...
