For my project Im trying to work out how to make one switch operate two different light bulbs. It's killing me and I'm nearly at the point of giving up. I can see it in my mind how to do it but I can put it into practice. Please can someone help?

I want to use a switch to turn a lamp on like normal, but when I flick the switch, repeatedly (x2) and quickly, the circuit changes to another lamp.

One lamp would be green and the other red (not that its relevant).

I was thinking about a 555 but it's been so long since i played with one I don't think I can achieve it.

Is their an easy way to do this job or is it as difficult as I'm making it!

I hope you can help.

Thanks

Davy

I came up with the switch though after using a security alarm that changes to permanently on when you double-switch.

For my project it has to be a single switch.

thanks

Hi davy,

If you talk about main powered light bulbs this is the trick:

Olive,

Your circuit diagram is absolutely unequivocally exactly what I need, thank you so much, I think it's an amazing circuit and I'm glad it served you so well, and for so long. An absolutely amazing, but emotional story, you sound like a great guy.

Thanks again! I will let you know how my project turns out.

Davy,

Happy that it's what you are looking for but the design is absolutely not mine.
I just point you to the right direction!
Doesn't mean that I am not a great guy too

Hi Sheldonstv
welcome to the forums

not quite what the OP wanted, If you read back through you will see he wanted 2 different lamps on the same circuit to be individually switched

Olivier
that was a great link I hope you and Davy both read the page right to the bottom. a bit of a sad story in may ways. But a nice tribute to Ronald's mom

cheers
Dave

Hi Dave,

Yes I have read the sad Ronald story to the end, that's why I was a little bit embarrassed with the littledavyboy reply.

This is a really awesome circuit. lots of applications. You could hook the super secret device of doom to an ordinary light switch. MUHAHAHAHA just kidding
