Dodgy Ignition Switch Norge

This morning when I wanted to start the machine it wouldn’t. Checked all the normal things battery voltage fuses all okay
I fiddled a bit with the key and everything lit up and it started BUT when the bars were turned to the right all went off
I narrowed the fault to the connections at the bottom of the switch
I now need to remove the switch to sort out the dry joint or what ever is amiss, BUT, how does the switch come off?
