The T6EX doesn't have a 3 position switch channel, so I had to combine channel 5 and 6 to get four modes. I made it work with a pot that has double terminals for each knob position, so that way there is always 2 pins to connect cables to for a single position.
Think of this knob as a bridge between same terminals: A to A, B to B, etc, closing the circuit to ground.
Channel 6 is connected to a terminal A and a terminal B from the opposite side.
Channel 5 is connected to a terminal B and C.
This is how the pot look like:
I got this switch at the Home Hardware in College st and and Spadina Av, Toronto, Canada. Sorry I don't have to much information about it. It's just a position knob.
Later, in the radio, I set up 2 PMIX mixes. they appear as PMX 1 and 2. PMX 1 it's at +70%, MAS (for master) is channel 6, SLV is channel 5, SW is channel 5.
PMX 2 is set to -60%, MAS ch6, SLV ch5, SW to ch5.
The final look:
Let me know what is not clear and I will edit this blog!

Ah I shall disconnect my ch6 then. Here is hoping :)
ch5 is the only channel I connect to the APM.
I'm going to check the radio programming one more time, just to be sure I wrote it down correctly.
Ok well I've been buggering around and still haven't got it right but I'm glad we are both on the same page now :D
Can you confirm what channel you are connecting from the receiver to the APM board?
With ch5 giving the different pulsewidths is it just that channel connected or both?
The intention was to have ch5 giving 4 different pulsewidths, but as a result of the connections, you get ch6 also changing pulsewidth. I use ch5 to change modes. If you don't connect ch6, ch5 would only give ON and OFF pulsewidths, like in positions B and C (ON) and D (OFF).
Position A: ch6
Position B: ch6 and 5
Position C: ch5
Position D: none
In conclusion: I guess it's wrong to say that the ch5 is the master of this whole mix, it's shared by both channels.
I hope you can make it work.
No. I believed this was a way to mix ch5 and ch6 so only one channel would output. The output would be of tangible relation to the pulsewidths needed for mode selection. The setup you have listed when using the radio test outputs both channels as normal but with slightly shift end points.
Did you intend to shift the end points (increasing the pulsewidth gap) or create a single channel that outputs 4 separate pulsewidths?
If you intended the second it hasn't worked for me I get the first and therefore do not get a four mode switch.
Any ideas?
Not really... What you are trying to do is make the pulsewidth gap bigger, right?
I have entered the mixes you stated and have connected both outputs (just to see). While watching the radio readout I see ch5 and ch6 creating pulsewidth and they are both producing (915ms and 2013ms) not a more specific graded pulsewidth from ch5 only. The switch is wired as you have done and the mixes are the same.
Any ideas?
Ritchie: yes, the mix 'master' is ch5
Olugbenga: I have no way to know about the 7C, I made it work on mine, but that's all I know.
the pot you can buy it from here:

and i'm sure many other sites. google search alibaba
Where can I get to buy the pot or potentiometer used above. I cant find any on ebay and ideas please? Also Cant the mixing be done as it is with Futaba 7C?
Just a quickie as I've just done this (ill post pictures in daylight) with the two channels mixed which is the channel the mix comes from?
The mix would dictate that the SWitch is Ch5?
