Because the only new production switch I could find is sold by Saber Cycle and is $169. I paid $26 for the 1100 switch. Plus if I paid $169 and it failed again... No.
I found 5mm EZ locks that have a 8x1.25mm external thread. I plan on getting a set of those to bolt the new switch in. About $5 for the inserts, $2 for bolts, $1 worth of spades, $26 for the switch, figure my time to build the intermediate harness (5 minutes).
