Small foot-operated switch which can be used multi-purpose, e.g. as PTT for a ham radio. Connected to whatever endpoint by a “simple” mono audio cable (guitar cable).

Unfortunately, the jack i used in my first version is no longer available - the linked one in the BOM must be sanded on one site to fit into the foot switch :-( But it works!

See also my FT-991a adapter, which i use in combination with this foot switch.

I am not responsible for things you blow up!
