[GreenKeys] Low paper indicator/ shut off model 28

[Stan Voynick]

I infer from Andy's description that the use of two separate switches is so that they can be positioned to trigger at two different times.   One is positioned to activate a "low paper" warning light, but the machine would be allowed to continue running for a time after that.  Then if the Teletype machine's human servant doesn't replace the paper roll in time, and it runs further down - dangerously low - the second switch would cut off the TTY machine power altogether to prevent running out and typing directly on the platen.

I want to make a low paper indicator light for my model 28 (just the printer) that would also cut the power to the machine, if left too long.  In my head Id have to have two switches.  One for the low level light and one for the power cut off.  If I figure it out I will make one for my 15.
