PTT for Maestro

Hello, using often a headset with Maestro, the KOSS SB45 is doing a god job.
But there is no PTT and I´ve searched some time to find something useable
Here now my solution: it is a remote button from Canon camera
called RS-60E3 costs about 12$.
It is a simple mechanical contact, made for a life time.
There is also a lock for the PTT... for longer QSO´s
I´v made a simple adapter from the 2.5 mm to 3.5mm  PPT plug for Maestro
But it is also easy to replace the cable in total.
Ceck the photos an have fun
