This ignition switch has 2 positions: On and Off. There are four male spade connectors on the back labelled 1, 2, 3, and 4. Chrome plated steel knurled ring nut. 2 rubber covered keys. These simple switches fit standard 22mm holes with the 180 degree locking slot engagement to prevent the switch from rotating in the hole when you turn the key. Total length ~54mm, length without the terminals ~44mm, largest diameter ~32mm.
A 2 position ignition switch provides on and off positions only, which means there is no key position that turns the tail light on while allowing the key to be removed.
Replaces original Ducati switch on 250 and 450cc models.
