Un reliable indicator switch

<< < (2/3) > >>

I Must own up and admit that after nearly 50 years of wearing leather jeans, I now use denim jeans, kevlar lined, and fitted with hip and knee armour.  Very comfortable.

The contact plate IIRC are like small U shaped pieces of copper. About 10mm in length. They are easily distorted and end up with one leg of the U longer than the other. This can cause it to jam every now and then and sometimes not make the contact you want so the indicators don't work.

I use a Dremel and the finest of my radial abrasive discs to clean all the copper contacts, the white disc is fine for this as it's around 2000 grit, like a pumice stone actually. The contacts shine like new after just a few secs. Never had a problem with them not working after. The white disc is so fine it doesn't even damage the bakolite holder a lot of these contacts sit in, like the kill switch etc.

A little dialectic grease and it's good for many years.

I tend to collect broken switchgear, keep what's good and bin the rest. I may have some indicator parts if it ends up broken inside.

Years ago I had trouble like this. It turned out to be an earth connection to the lower of the three bolts that hole the headlamp sub-frame. After cleaning up a bit all went well.
