PC disconnect valve

[Meshach]

After a few years of hand flying, I’d like to see if I can get the PC to work. But I’m missing the piece that goes in the yoke. The rest of the system seems intact. IIUC, without the valve, the system cannot work. 
 

Does anyone know where I could get that little piece/button that goes in the yoke. 1970 F.

Check eBay, perhaps for an entire yoke. Perhaps @Alan Fox has one. Alternately, you can retrofit with electric solenoid, but that is obviously more work.

I prefer an on/off toggle switch so I used this one

I like the button on the yoke.  Becomes very automatic to press it while turning the plane and then releasing it to let the wing leveler reengage.  Recommend looking for a Mooney yoke on eBay.

This is the switch I installed in series with the yoke pushbutton in my last Mooney, a 1967 M20C.

Having the on/off toggle and a functioning yoke switch is really the best of both worlds.  Turn the toggle on and the PC works normally.  Turn it off and the airplane flies normally.

I used this toggle switch as well. I like it better than the old knob.  It’s a switch on the dash and now I have a ppt on the yoke.

Another possibility.  Not an aircraft part.

I have one you might want and sent you a PM.

I have an actual Brittain PC disconnect valve I will sell.  PM if interested and I can share photos.  Ths is for panel NOT yoke button.  It is a push pull.

I like the idea of a switch on the panel. I assume that’s a minor alteration that my A/P should have no problem doing?

I am not looking to buy but would be interesting to see the photo. What year of Mooney would have this on the panel?

[Echo]

Brittain made and sold them as well as an electric solenoid to cancel p.c.  An vintage Mooney with a Brittain system could have them.  Most came OEM with yoke push button disconnect.  I prefer to NOT hold the button while disengaging p.c. and wanted a push to talk button integrated in yoke so push pull was installed.  The line for disconnect was pulled back through yoke and shaft.  Drill a hole in panel.  (I already had a hole where ram air cable was)  I removed cable as I have a J cowl with no ram air on plane.  Screw in push pull manual dump and attach line.

Or keep the yoke button, and mount a Push-to-Talk like this . . . .

My old B had the push/pull switch vs yoke button…

I changed yokes out on my C and may still have the button. Let me know and I’ll look for it… is for older style yokes.
