[asphalt guy]

anybody have a picture of how the front brake light switch goes together on a 1981 gs550t i took mine out to do some repairs and it fell apart now i am not sure how it goes back together i did see one on line and looks like i did find all the parts it just shows the parts not how it goes together

Now that you know it comes apart :shock:, you can take the clutch switch apart a little more carefully to see how it is supposed to go.
The switches are basically interchangeable. 8-[

First of all, it's very hard to assemble the brake light switch with the master cylinder on the bike. I suggest you take the master off and flip it over before trying to assemble it back together.

There is a slot/notch in the the brake lever that the sliding contact fits into.

The order of parts that fit into the slot are - spring - plastic holder - U shaped electrical contact - circuit board with wire attached - plastic cover w/screws.

The circuit board and plastic cover can slide back and forth to adjust the sensitivity of the switch. Install the parts but keep the screws loose so you can adjust the switch. Snug down the screws when you get the switch where you want it.

Hope this helps.

Good luck.

I use dielectric grease to install without removing the M/C. Grease the plastic thingy so it stays in the notch and install the cover. If the spring won't stay inside because the contact won't snap in anymore bend it a bit so it will.
Order of installation/ Plastic fits into notch of brake lever. The spring goes inside the plastic part and the contact snaps over the spring. The contact moves back and forth on the little circuit board that the screws hold everything together.
If you can't it together they are dirt cheap on Fleabay.

If you can't find one on Fleabay, new ones aren't very expensive, either.
