When the Normally open contact reopens following contact, a back spike is carried to the FWBR and stored in the Capacitor.

It was kind of tough to film this and run the oscillator manually at the same time. This proves that the wireing is correct. The hot wire goes to the Normally Open connection along with the FWBR!

Look at the size and heavyness of the magnet stack. Extremely powerful attraction, but sufficient to work with the clumsy DPDT limit switch.

A pair of wooden salad tongs holds the switch. A rubber band pressures the switch.
