add hat switch to yoke

Hello, I have read forum postings around the web where people have added or suggested adding Leo Bodnar hat switches to their existing yokes that didn't come with one (i.e. Yoko),  Has anyone done this successfully?  It sounds like you could just mount the hat switch on the side of one of the yoke handles, no biggie.  However, when I saw the switch on the Leo Bodnar site, i noticed  that it doesn't have an enclosure (It's just a circuit board, with the switch and some wires that I guess go to a Bodnar board).    Is there an enclosure that you could put this in so it looks more integrated?    I've googled and googled but can't seem to find any pics of a Leo Bodnar hat switch on any flight yoke.  

Thanks

Bill
