For clarity, let's call the three studs A, B and C.  
A is the stud connected to the switch, but not the fusible link.  
B is the stud connected to the switch and the fusible link.  
C is the stud connected only to the fusible link.

One power lead (from the front battery pack on my E12) goes to 
stud A (switch only).  The other power lead (to the control 
solenoids) goes to stud C.  Stud B is not used for connection to a 
lead, just to allow replacement of the fusible link in the future.

This way, the fusible link and the switch are in series, and both are 
capable of disabling the power circuit.
