I've always been curious about what is in these and what is likely to fail.
On the early switch the housing was cracked so this not a loss of good parts. There is a
load of dielectric grease in the early switch. The late model aftermarket switch was hacked and put into an early ignition cyclider, so again, not a loss. There really isn't much in here that is serviceable. If the contacts are worn, there isn't much that could be done.
However, you can definately tell the later style aftermarket switch is made more cheaply. I can see some evidence of arching between the center contacts on the late style switch.

A quick Google search didn't turn up any photos of these switch internals so I figured I'd post just in case anyone else is curious about what is in there!
