Wiring help on pump system for a CNC Plasma Table

[Duker]

I trying to wire up a switch for a pump to fill a plasma table with fluid as well as a switch to turn on a normally closed Selenoid to drain the table. I have the switches wired up using a 4 conductor cable whose colors are spelled out on the crude schematic attached.





The issue I have is that while it works the single gang two rocker switch i am using is that the switches are reversed from each other in the off position and opposite when turned on instead of in alignment. I am sure it’s a simple fix but for the life of me I can’t seem to see where I am off. If someone sees my rookie mistake I would most grateful for the help and any obvious grief I deserve. I will even throw in an AWD as a bonus for the help!

Thanks

If these switches are similar to ones I have seen, first of all, you could just pop one of them out, twist it around 180 degrees, and put it in facing the other way. Just don't let the wires short out to each other.

Or you could pull the wires on the outer terminals off and reconnect them on the opposite side terminals. See pictures: move the wire from where the red line is, to where the blue line is:

If your switches don't have the spare terminals on the opposite side of the center ones, then the only thing you can do is to push one of the switches out, rotate is 180 degrees, and snap it back in.

The first thing I see wrong is that you are switching the neutral instead of the hot wire. That is a safety issue because if someone was working on the machine and they had the switches off there would still be power going to the pump and the solenoid.

As far as the switch direction you just need to flip one of the switches over in the box.

Also I would have mounted the switch box horizontally so that when you pushed the upper part of the switch it would turn it on and the lower part off. Makes more sense that way.

Thanks for the reply. I can switch the wires on the switch which will correct the alignment issue. The thing I can’t wrap my mind around is why my drawing has a hot leg on the other side of the switch when they should be the same. But I guess I won’t argue an easy fix. Thanks again.

Ok thank you that’s what I was thinking was happening but I guess I have looked at this wiring mess so long I was becoming biased as to what was wrong.

yeah dont switch the neutral. switch the hot (black)
