What the hell is it good for?
This box houses a wonderful mechanism that accomplishes the wonderful task of switching the machine off.
Inside tha box...

The potentiometer on the controlboard is shorted, and the board reverses the servo direction. The lever goes back till it hits S1 and switches the machine off.
