DIY Tesla Switch Guide

OK - The relay is what leads in... on my previous diagram-post
in the circuit by L.Pollaehn? Then the +12V goes to power the
timer circuitry?

I may be understanding this a little better now if my
guess is correct -

Hi Geotron,
I would connect the top end of the relay pole through a 1K resistor to the 12 volt line, also connect the same pole to "timer input" next connect the centre pole to common ground. The relay then provides pulses to the timer input between 12 volts + via 1K resistor and ground.

Loner - when you refer to the cap in the timer section
of the switch, do you mean the one labeled 3.3MF? If so,
by decreasing the size of this cap, you're saying it
would have the effect of.... increasing the rate of on/off
signals?  What is the purpose of having the timer chip
and everything when the capacitor is what controls the
signals? I'm probably jumping to conclusions on this one,
and if so I apologize.

Well, here it is - a modified diagram with the 1K resistor
and everything connected the way I'm picturing it ought to
be... looks good?

I'm not really certain what purpose the
1K resistor serves... is it to direct the flow
of electricity? The way I have illustrated it, it
looks like the +12V will go straight through into
the Timer Input on the Switches, bypassing the relay -

The diode configuration looks to provide a push pull type of arrangement, when the relay is closed one set of transformers is conducting more than the other set, and when the relay is turned off the BEMF affects the others that were not conducting. The 1k resistor is for current limiting since the relay is effectively shorting the power buss to produce the pulses. This is the timer circuit BTW, as shown.
