I need to "design" a on/off switch for main (230V), and it need to be covered with a printed "keyboard" film.
For safety I want to avoid using a IO from tha AVR (if it lock up you can't turn the thing off)
I have found a microswitch for 230V (for PCB mount), but not one that is latched are there any?
I could make it with two switches (a make and a break one).
If I have make it with a NO (make switch), are there a simple way to make it turn a relay on if off and off if on ?
(not to big :) )
