Why do you need it?
I assume the front brake lever wont turn the light on since you recently replaced/fiddled with the lever and the little nub came out?
I have not replaced fiddled with the lever, but someone may have at some point. I did notice that the little rubber "boot" was not on the actuator portion of the switch. Is this a common problem. I found a replacement of a newer 748 but it didn't fit. Mine mounts with 2 little screws. This one had press in tabs that don't align with the holes. I have decided to quit playing around and go with OEM.
DUCVET - Thanks for the #. Where did you find it so that I don't have to post again for the next little part that breaks?
