Curiosity killed the ? got me in trouble.

[Charles Mueller]

'I'm starting to figure out the wiring for the PT-26 I've been
restoring. During that process I got curious about the condition and
inner workings of the plug/switch that allows an external power source
to be plugged in. My parts books don't have a description or number
for this plug/switch. The backside has 3 terminals, marked B+, B- and
M2. The front or outside side has a spring-loaded plate that rotates
to expose 2 sockets that an electrical power plug can be fit into.

I was lucky ? on easing the two halves of the plug/switch apart I
heard the internal spring hit the roof of the hangar, and two steel
balls simply rolled out onto the workbench.

The lucky part came when I turned around and found the spring resting
on the floor behind me. The visions of having to scour the hangar I
work in dropped away and I retracted the various words I had expressed
when things got a bit wild.

Anyway, reassembling the switch was a challenge, but I was able to do
that with only the 2 steel balls left over!

I have a sneaking suspicion it would be a good idea to get those 2
balls back inside, one on each end of the spring. Now for the begging
part ? can anyone help me by describing how the plug/spring can be
properly reassembled? Any suggestion will be greatly appreciated. (I
already understand that it is best to not take it apart, especially
since the interior contacts were in excellent condition.)

I've added a photo album with a photo of the switch interior, and one
of the project as it was about a year ago. Since then the engine has
been hung and wings are now ready for cover. The album title is N69167'
