Hello, I have a project where i have to create circuit that works as follows: There is two lamps(1 lamp is replacement lamp), when turn circuit on, active lamp lights up, but when the lamp burns out, replacement lamp lights up.
My problem is that I dont know how to make a switching and circuit is designed to work with an AC 220V 50Hz 60W lamps.
I have found so far that of the switch i can use thyristor or relay but if i use relay it switch and then turns of, because if it is turned on or there will be magnetic field what will make problems with the antenna what is really important.
What i want from people of this forum: what can you recommend, how to realize this?!
Thank you for your attention
p.s if you think for what i need this type of circuit, it is for safety because there must be light all night.
