momentary pb to constant on

Maybe this x2...? Can sort out voltages and switch filtering later...

WOW!! that is way over my head . 

I found this device http://www.amazon.com/PAC-TR7-Universal-Trigger-Module/dp/B0002J22BO and think I will give it a try.

Thanks,

Yeah - I was brief. The CD4013 is a 14-pin chip (Integrated Circuit) that costs $1 and contains two "D-type" flip flops which you connect as T-types (ie, Toggle) by interconnection inputs and outputs as above. The other stuff is an output transistor or buffer in case the 4013 (or whatever chip is chosen - there are others) hasn't the strength to drive your output, and some power-supply protection to limit it to a smooth 15V DC or less... But that's electronics. A silent $2-$3 solution in a matchbox, but needs a bit of knowledge and soldering.
