AI Thread Summary
To create an AC circuit with two light bulbs and a switch, a DPDT (Double Pole Double Throw) switch is recommended. One bulb will light when the switch is open, while the other will light when the switch is closed, achieving the desired effect. The discussion emphasizes that using a DPDT switch is straightforward and requires minimal components. Participants express relief that the setup is simpler than initially anticipated. Overall, the circuit design is confirmed to be easy to implement.

Hi I want to make a circuit with AC and 2 light bulbs and a switch. One light bulb will light when the switch is open, but will be off when the switch is closed. The other bulb will have the opposite effect.
I tried to use transistors but that only works for DC current.

You want a simple DPDT (Double Pole Double Throw) switch. What you are describing is a common use of a DPDT switch and you can buy them at any hardware store.
 
Thanks, thought a bit too difficult.

Sorry, I don't know what you mean. Do you mean that you though it would be difficult and are happy to find out that it is easy or do you mean that you think a DPDT switch is too difficult? There aren't very many things more simple than a DPDT switch and for what you want to do there is NOTHING that is more simple.
 
What I mean is that I thought it would require a lot of parts, but turns out it's that simple.

Yes, good. It IS simple.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
