10 terminal rocker switch wiring diagram for reversible pump

[Scottie]

Here's a wiring diagram for a 10 terminal rocker switch used with a reversible pump for ballast wiring. I'm not sure many people are using these, but if you need an on-off-on switch with something other than red lighting, a 10 terminal switch (Carling VJD2) is really your only option. I scoured the internet for a diagram and they're prevalent for the common 7 terminal, but none are available for the 10, that I could find. So I had to figure it out for myself, but thought I'd make a nice diagram so that maybe someone else can save some time.

10 terminal switch wiring diagram for reversible pump ballast installation

Small note: you have a 25A spec'd in your drawing. That should exceed the draw from your pump by at least a bit, and should also match the wiring sizing for the length of run. If your pump has a 10A draw and your wiring is designed for 10A, probably a 15A would be more appropriate, for example. Similarly, if your pump drew 30A (which would be pretty darn big, I admit) and wiring to match, I would probably do a 35A.

I installed Jabsco Ballast King pumps. They pull 19A and spec a 25A fuse. Wiring is 12ga.

Thank you - this was very helpful. My application involved the Contura II actuators which requires the top lamp to be always on with the ignition and the bottom lamp to be on if the actuator is in the up or down position.

I have used a DPDT 6 pin on a valve to open and close by reversing the polarity. Much simpler design...

If you remove the lamps then the design is the same except the connections are using different terminals. My post was to assist others with a different lighting requirement.
