Hello,
I have an existent 12v 20mA lamp driver with a momentary push button "on-(off)" type. The push button is closed initially , when pressing it, it goes to open circuit and the lamp lights.
I need to modify/rebuild this electronic circuit using the same button where it can toggle between on and off , start condition when the equipment powers up, the lamp shoud be off.
I could has changed to a latching mechanical switch, but no space there, have plenty of space inside the equipment and would like to use electrtonic circuit instead.
Any ideas ?
Attached is the circuit diagram.
Many thanks!
George
