Polarity, trigger, & bias scheme

This will be uncharacteristically concise as my new job + domestic duties = dead-tired Prof. Gomez.

So! It occurred to me I hadn't posted how the switch was to be biased, triggered, etc. here it is, hopefully you can make it out:



Note that power dissipation in the biasing resistors can be non-trivial - we'll need high voltage, high value, reasonably precise resistors for this purpose. Naturally none of those I have lying around are even close to the correct values...
