Switch, Booby Trap Murray) Mark I Switch, Combination, Mark 2, (Aust)
 A combination switch developed during the Second World War.  It used a modified .303 cartridge case for a fuze or detonator lighter.  Able to be transformed to a pressure, pressure release, or pull switch. If anyone has any particular information on this combination switch it would be appreciated.  About all I know about it is its Australian.  Obviously developed from the Murray Combination Switch.

This is the Australian switch that the US has adopted.  Also used by Canada as the F1A1.  The British have also adopted it as the L5A1.
