PTT switch for 172N

Hello Cessna owners !

I want to add PTT-Switches to the controls of a 1977 172N.
Since the control horns are not hollow i don`t know how.

Any suggestions ?

There are PTT switches available that attach to the controls with velcro.
The wiring runs externally.

my friend's cessna 150A has the same problem.
I made up aluminuim clamp blocks that mount on the control tube hard
up against the front of the yolk. the side of the clamp block has a
recess that the switch is mounted in. switch sits up just proud of the
clamp block. press your finger down on the top of it to talk.
cable is a curly tail down to the panel under the control mount.
it doesnt limit the control movement.
has been in use about 4 years now without mishap.
friend and his LAME love it.

My old flying club in NY purchased four rubber (plastic) covers with a PTT
built in. They slide over the horns of the control wheel and have a curly
wire into the instrument panel. They worked great and have been in use for
four years. I don't know where they were purchased.

I used C150 horns for my homebuilt and with long drill bits bored holes
through for both the PTT and AutoPilot.

I drilled some very small holes in the backside of the control yoke and
gently tapped them to accept a small screw. Attached a piece of
aluminum with a SPST NO push button switch from a local electronics
store. A curly cord attached to the yoke with a cable tie and thru the
inst panel with a strain relief. Seems to work well and my mechanic
had no problem with it. Only regret is that I didn't buy a high
quality switch and may have to change it. I didn't invent this whole
idea, I stole it from the folks on the group. You know who you are
