Current reversing eliminates the core saturation one would otherwise encounter with a simple pulse circuit. This circuit actually generates power.

@synchro1


Anyway you could post a circuit diagram in addition to your photos? It's not clear to me what your doing for sure.

Thanks!

I wrapped the 2 ND connection around for greater strength.

@Truesearch,


These 2 SPDT switchs have the same 3 electrodes as the limit switches. The NC or normally closed contact wires directly to the NC electrode on the twin. The NO's as well, and the Coms to the positive and negative of the load. I am using a thick 16 gauge uninsulated copper wire to double as a frame. The power connects to the 2 wires respectively, NO's and NC's.


I mistakingly connected the Coms with the wire in the middle when the wire should connect the top 2 connections.

The traveller spring clips over the top wire.. Both top and bottom wires wrap completely around the switchs so both electrodes have 2 wires connected.

The black and red clip wires show where the positive and negative of the power connect. They will work reversed.

Here the variable resistor is connected between the positive and the bottom wire.

I plan to run the Com wires down to form "Grasshopper legs" that balance the switchs on the perpendicular.

The Com wires are supporting the siamese switchs like a cradle :

Side view. Notice the switch blades lay flat against the sides of the plastic spring.

These cube magnets are extremely powerful and are very difficult to seperate.

The two switch flanges are simply taped to the plastic spring with electrical tape.
