i've asked directly at voti, here is the reply: > - Is it vertical mounting or horizontal? If PCB-mounted vertically. Can also be front-mounted, but the connections are straight (not solder-eye type). > - What kind of shaft it has? isolated (plastic) 5mm diameter, 13 mm long (from end of thread), flat side, groove at the top. > - Is the metal collect threaded? you mean the part that you use for front panel mounting? that is threaded, and the nut (or is that called bolt?) is included.
