Flasher Switch Rebuild

[one4house]

I took the time this weekend to break open one of the flasher switches. This was part curiosity and part inspection. I was at the local junkyard and the owner just gave me the switch. I had nothing to lose if I broke it so decided to do a little write up.

Come to find out, these little guys are about as simple as can be. The one I had was suffering from a case of corrosion. Because of this, I decided I would break it open and try and clean it up. I do not know what I was expecting, but is is a very simple switch that can be taken apart and cleaned quite easily.

I did not think about getting pictures of my switch in the "corroded" state. What I can tell is that I use WD40 and a Brillo pad to rub the corrosion off of the metal terminals and body of the cover. If you look at the pictures below, you will see that these parts are very easily saved as long as you have not had a terminal corroded all the way through.

This first image is all of the parts spread out after cleaning.

Here I turned all of the 2-sided parts over.

A closeup.

The two long springs and the plastic plugs drop in these holes. If you look closely, you can see the springs in the holes.

Now reinsert the plastic pins and put the assembly back on the case with the plastic pins facing in.

This is the last image I got of the assembly before putting the plastic cover on. Both of the small terminals are the same size. They go back in on top of the little springs.

Now you can put the plastic cover with all of the terminals back in to hold everything together. I do not know why I expected these switches to be more complicated. With a steady hand and a little WD40, you can have most of these switches restored in under a hour.

Any questions, just let me know.
