HELP!!!!!!!!!!!
I am using an S700 2-50 switch to activate my fuel pump. So far I have been
unable to brake the code. I have so far used multiple schemes .......I can
get it to work to this point....toggle down OFF.....toogle mid position
(on)......toggle up notta?????????????...for the momentary on. Right now I
have #2 to power bus, #5 to ground, #1 to pump motor...red, #6 to pump
motor....black , and #3 to #6.
Thanks for any and all suggestions.

Frank,
Are you trying to control another device besides the pump with the switch?
Like a primer with the momentary on?
If so try this:
2 to power buss
5 to aircraft ground
1 to pump motor red
5 to pump motor black
1 to momentary contact device positive
4 to momentary contact device ground
This would keep the pump on while the primer is momentarily energized. ( by
switching the power buss lead of the pump and the ground lead of the primer)

Frank,
On the Z-11 drawing it shows that the power from the main bus goes to #5
with a jumper to #2. Why do you have a ground on #5? The grounds go on the
other side of the fuel pumps and it shows both of them grounded to the
panel. It seems to me that the way you describe it you have the switch
shorted out.
I am not an electrical genius just another guy wiring up an RV so I hope you
get some other suggestions.

It appears that all roads as they say lead to Rome or in this case to the
motor working. #2 to power bus, #5 to ground #1 to red wire from pump motor
# 6 to black wire from pump, #1 to #3 gives me continuity in toggle mid and
momentary up position.
Thanks for the help I am still wrestling with this is the final results for
the aux fuel pump/prime.

Frank,
Are you using the AeroElectric schematics? If so look at the Z-11 figure and
you will see that to wire the fuel pump and primer you come off of the
endurance bus 3 amp fuse with a 22 awg wire to the #5, there is a jumper
that goes to #2, then there is a 22 awg wire that goes to the primer off of
#4 and a 22awg to the fuel boost pump off of #1. There are no grounds off of
the switch. The devices you are trying to power are grounded at the device
or run a ground from them back to your ground block.
I wired my switch just like I described and it works just fine.
How are you numbering the switch pole positions. With the keyway pointing up
and facing away from you. The numbers are from the bottom left 1, 2, 3 then
on the right bottom up, 4, 5, 6.. www.aeroelectric.com/articles/switches.pdf
The 2-50 switch is a real neat switch, it is an on-on-on switch. Perhaps to
get the switch to do what you want it to do you need an different switch?
Maybe next week when everyone is back from Oshkosh you will get a better
answer. I am heading out for the weekend to go hiking and camping in the
mountains, first this morning we will do some hovercraft flying. Good luck.
Mike

Frank,
I just realized it doesn't matter how you number that poles on the back of
the switch as long as you know that the two poles in the middles are #'s 2 &
5. The switch is actually 2 switches in one with the power lead going into
the middle position on each switch.
Have fun.
Mike
