[smiley=steinigung.gif] Been one of those kinda days, eh?
There may not be much you could do to repair the turn signal switch. They can become rather fragile as they age... switches
and riders.
Troll eBay for a replacement. They show up rather frequently at reasonable prices.
When my turn switch went gerfunken, I bought a complete good, used handlebar switch cluster from RePsycle BMW in Ohio USA.

They can, on occasion, be slow with email responses but I always call 'em. Ask for Mark or Marco. Good guys.
In the meantime, you could disconnect the turn sigs and use hand signals to stay legal- if that's legal in Aussie-Land.
Hope your luck improves. There once was an auto rally known as the "Carry On Regardless". What was the line in Monty Python's
Life of Brian...
"Could be worse. Could be raining."Monte
