clutch micro switch - Ducati.ms

Hello all.
I have an 03 st4s and it won't start when it's in gear and the clutch is pulled in. I've discovered that the mirco switch is damaged and I need to replace it. I'm having trouble isolating the part number and so is the dealer. I've looked in the mircrofiche and found the switch/wire but the listed discription says it's a clutch drive pump, which it's is not...has anyone purchased just the switch and if so where? I've been keeping an eye on ebay but nothing yet....

The clutch micro switch on the 2003 ST4s is a piece of crap. When mine gave up I fitted a microswitch the same as the brake one, the master cylinder casting is already drilled for it. I had to make a small pushrod with a flange on it so that it won't fall out when the lever is pulled to actuate the switch.

Just checked my parts book, & the clutch micro switch is not shown or listed, though it is probably the same as a 916, 996, 998 or a Monster of a similar year.

The clutch switch is shown in the parts list I have but is not listed separately. It can only be purchased with the complete master cylinder assembly.

It is listed though for the S4R which uses the same master cylinder. Part # 539.4.033.1A
