Latest update,
Amazon USA failed to deliver, further ferreting about revealed the correct switch for my 2003 manual coupe with same SLS384 part number from a UK supplier..........all good except it is the wrong switch. Today I removed the original one which has only 4 contacts, not 6, and a shorter push rod. See photos attached. The switch is a very common type and fitted to many different vehicles, the part number is 0015450109. Just be careful to get one with the correct length of push rod.



Correct switch on the right 0015450109
