I'm working on a project that intends to introduce a replacement for the electrical switch due to hazardous issues. I meant by the electrical swich, the one we use at home to switch the lights on/off.
the replacement will be a fiber optics link fed by a LED and connected to a photodiode. bascially when I press on the fiber link, the light intensity decreases, and the photodiode get less excited (voltage decreases). this property allow me to use a comparator circuit to drive an open loop thing. but my issue is the following. the pressing will be momentarly, like what we do with electrical switches, but I want the effect (namely the light being on) to be constant. and when I press on the fiber link again, the light will be off.
I hope that clears everything. and I appreciate any help.
