Clutch lever switch

[Hook#3287]

I/S won't start in gear with clutch lever in.  Checked continuity at the switch and it only works in a small part of the pin being pushed in, all the way in, it does not.

I'm going to get a new one, but was wondering if anyone every had one apart?

It's definitely a non service part, but so are the starter buttons and how many have those been serviced?

Just looking for some guidance before I take it apart

I wish I could help you Bill. I've been lucky and never had to mess with one.

As with other micro switches I've dealt with on other equipment, contact cleaner, compressed air and motion. Hope for the bets. Some do have separation points and will go back together maybe needing a drop of glue. Its all 50/50.

I have repaired them with electrical contact cleaner sprayed into a little hole in the housing. Work it with your fingers and recheck with a VOM for continuity.

I didn't consider the contact cleaner, good suggestions, thanks, I'll give it a try.

This is the second bike I've had this issue on, the not starting in gear one.  I must of rode around for a couple of months that way, thinking every time I tried starting in gear "I gotta fix that" then completely forgetting till the next time.   When I finally remembered to look, one of the wire connections was off.

The Contact Cleaner worked

Until it dried up, that is 

The VERY VERY SMALL contacts inside the switch seem worn out.

New switch ordered, used one borrowed from a different bike, all's good.

Thanks for the help.

It must be nice to have 5 bikes to steal parts from.  Glad you figured out what was going on.

Something else to try.  After you get it working with electrical cleaner, blow out with compressed air and then inject Dielectric paste to fill the void.  Then, if possible seal the holes.  I've done this with many other switches and it works very well in permanently keeping out moisture and preventing air from getting to the electrical contacts.  Sorta a poor-man's 'hermetically' sealed

Learned to ride in the 60's/70's on bikes that didn't have a clutch interrupt switch, muscle memory now in always grabbing the clutch to start.

Mine started doing that a month ago. I thought I was going crazy. I've always been able to start in gear with the clutch pulled. I started questioning my memory...

Guys from Oxford need to read the complete post.

Us Brimfield guys usually just wait till the Flea market comes to town and hope we can find what we need there.
