6th Switch position

[steviemac]

Good afternoon chaps, I'm looking to source a switch for the 6th position (below right hand heated seat switch). I'm not prepared to entertain the long and tedious search for a Funk switch, and the resultant hole in my wallet that would ensue. I know I can make one easily enough, but the switch fascia would be blank. I've noticed the switches in a Seat Alhambra look pretty similar, but haven't found one in a breakers yet to try it.

Has anybody tried this yet, and if so does it fit properly? And would you be able to supply a part number? When I've looked online I'm only getting details for a switch blank
