If you're not inclined to fiddle with additional magnets, and have a bit more space,

just use a double coil bistable relay with two small reed switches placed ~3/8" apart.


Install some sort of indication when the relay is activated, e.g. a LED etc.

In case you want just ONE 'Magic Stroke On/Off', try this:

My attempt to use a Latching Hall Effect Sensor,

to turn lights ON/OFF with magnets.

You might like to try this circuit.
It is similar to my buffer 'Charge/Run' circuit, which is working well.

The two reed switches either charge or discharge the capacitor,
depending on the direction the magnet is swept, standard stuff.

The 1uF capacitor must be a low leakage type (ceramic is good).  
When charged the FET is on.    

The FET must have a good G-S voltage  (IRFD014 is +/- 20V)  
If a surface mount FET is preferred, then BSH108 is the one I use.

Regards to all

Steve
