Go on, £55 for a bloody switch and no hero shot, wheres your priorities man? We demand a photo.
It's an AML 30 series switch, same series as the ones used on most Bedini amps (25/25, 802 etc).
The actual item that I've used is a Master Battery switch from a Robinson R44 or R22 helicopter

The Strobe, Alternator and Nav Light switchs are the same but plain black.
