Our club's PZL Swidnik PW5's push-to-talk switch is starting to fail.
We looked at it briefly and it was not immediately obvious how it
could be removed from the control stick and replaced. The maintenance
manual was no help. Has anyone worked on one of these?

usually PTT switched are simply pushed down into the control stick grip and
not attached or installed with a nut or anything from below since it's
almost impossible to get a wrench in there and you can't use a socket there
either since it will already have the cables installed on the switch.this is
not a problem since you are always pushing down on the switch, never lifting
it......
a PTT switch is also a simple Normally open switch, 2 leads in and when you
push the switch you merely make a completing of the two leads and the PTT
circuit is then grounded telling the radio to transmit (keying the switch
is like connecting the two wires to make one)
I have these normally open switches that can be bought for just a couple $
at any electronics supply, but cheap switches are.well cheap, plastic and
prone to failure.I also have expensive all metal switches with a very
positive "click feature you can feel.

these in my own aircraft..they are expensive, but always work and last ....

Hi Roger,
Some gliders have a stick grip with a slot to allow a nut to be attached to
the back-side of the PTT switch.
I highly recommend the metal switches I sell here:
http://www.cumulus-soaring.com/misc.htm#Switch-PTT-EAO - without wires
or here:
http://www.cumulus-soaring.com/dittel.htm#F10050 - with wires
Best Regards,
