This has got to be the clearest explanation of basic switches on TH-cam. The fan and blow dryer analogy makes the concept so easy to visualize. Thanks guys!
as of 10 minutes ago I didn't know these things existed..after finding this video I feel like I'm armed with all the information I needed. great video. thank you
I have a ceiling mounted fan, the switch fitted is a single pole single throw (a light switch) I have been told I need a double pole double throw switch to isolate it. There is only a live and neutral
this is the best video i have ever seen on explaining switches!! Thanks so much for the help and the advice. You are very professional and knowledgable. God bless you and your family.
Hello, I have a 20 AMP double pole switch that works as follows: Its a Light switch in a guest bedroom with a Neutral (on the Top Left), Black Hot wire (on the Top Right) and Red Cable (on the Bottom Right). This Bottom right cable is only HOT when the master bedroom light switch is turned on). The Bottom Left terminal is blank. The house was built in the 20's and this setup I am told was used as security feature to turn on lots of bedroom ceiling lights from one dedicated switch in the master bedroom. When the master bedroom switch is in the ON and the Red Cable is hot the guest bedroom light switch remains on thereby keeping the ceiling lights illuminated. Can you describe how many throws it has? Thank you!
I'm looking for a very specific button switch. It is DPDT momentary with NO OFF STATE. I want to connect Plus-to-A, Minus-to-B while it's not pressed and Plus-to-C, Minus-to-D while it's pressed. I see 'dpdt' used to mean all kinds of different things, but it seems like all of them have an off state. if any are exactly the thing I need I can't tell for sure. Is there any sequence of exact words that will be used to describe exactly the kind of switch I need to find?
Hi thanks for the great video. I was just wondering. Can you put just two hot wires from a two pole fuse holder in a three pole overload (ex. L1✓ L2✓ L3×)?? Thanks again
If I want to replace my water heater timer box with a a switch that moves power between the water heater and a 220v outlet, (for 16A or 24A ev level 2 charger), would that be a double pole, double throw switch? Would the Leviton 1288 switch work? I have solar hot water and I only need to turn the water heater on like once a month. Thanks
Can someone help? if you have a light switch in the long hallway, you have three switches that can turn on and off at the beginning/middle/end of the hallway. Would you call these as Single pole, triple throws? thanks for explaining.
Hi! Two of the three switches in this circuit are called 3-way switches and they are SPDT (single pole, double throw) switches. The third switch in this circuit is called a 4-way switch and is a special version of a DPDT (double pole, double throw) switch. It’s special because the throws are shared between the poles. Here is a short article describing the wiring. joneakes.com/jons-fixit-database/1729-Can-I-have-three-light-switches-controlling-one-light Thanks!
@@ESwitchInc so in this situation , we call this as double pole double throw? And if it's only two switches, then it will be single pole double switches? Let me know if I am wrong. Thanks
Thank you, glad we could help! E-Switch provides STEP files for thousand of switches. Check out the link on how to download or request a file: th-cam.com/video/eGqa48d0EXY/w-d-xo.html
Why is it so hard to find a 1P1T rotary switch? I just need to mount a simple ON/OFF switch and need it to be rotary to match the rest of the input selector and volume knobs in the control board of a stereo system.
There is indeed. But it seems out of stock and unavailable to purchase online.@@ESwitchInc I've been struggling to get this from aliexpress or even custom made from alibaba (need more than one unit... for a business project) and have had zero success
Maybe somebody can help me with this. Say for ex: I have microphone A ,B, and C. The switch has 2 positions. In position 1 microphone A and microphone C go through the switch. In position 2 microphone B only is allowed through the switch. Regardless of the position the output of the switch goes to a speaker. Rather your on position 1 or 2. All microphones are on the same speaker. But not at the same time. 2 inputs. One output. Would this be a double pole single throw? Thank you in advance to anyone that offers advice. (Its actually for guitar pickup wiring.)
On the surface I would say it’s a double pole/double throw. In either position 1 or 2 there is a closed circuit (microphone closed) so that would make it a double throw since each position has a closed circuit. On the number of poles, it appears that in position 1 they have one separate pole for mic A and another separate pole for mic B (A & B are wired separately to different terminals on the switch). This would mean 2 poles (even if doesn’t use both in position 2). However, what isn’t clear is if you wire both “A” & “B” to the same closed circuit. If you do, then it would be considered a single pole/double throw.
Hello thanks for the video. I would like to ask please which switch I need: I would like to have two independent circuits which switch on at the same time but remain independent of each other. I have an interface which mimics keystrokes (when a switch is closed) attached to the PC via USB but I would also like the switch to operate an LED at the same time (this would be repeated with many of the switches), however the LED is attached to its own power supply and do not want the current to flow into the interface, or PC. Am I correct in assuming I need a DPDT on/off switch for this? Thankue for your time.

Can you replace a 15 amp, AC, 2 pole, single throw switch to a water heater with a 1 pole, 1 throw switch? Currently the switch has a pole for the positive and the negative for both in and out or on and off. Could either the negative or positive wires be wire-nutted together and use a single pole switch to open and close the other wire or circuit to open and close the circuit?
Hi, thanks for your question: Electrically, 2 poles aren’t needed (assuming the switch contact can handle carrying the current required to run both devices). There may be other application restrictions (i.e. proximity of the fan & light) or building codes that require this be done with 2 poles.

If I read it correctly you want a 1 phase to be used as a 3 phase? That can't be done as the phases are 120 degrees seperated in the sinus wave. 1 phase keeps being 1 phase of 230v It never goes to 380V Nor will it increase your amps, if you got 16 amps at the start it can only remain at 16 amps. If you got 1 liter of water, it will still be 1 liter even after you used 300 cups to poor it in. What you start with is what you end with.

That's great to hear! Thank you!
By far the best video I have seen on this. Clear and crisp.
finally someone explains poles and throws properly that does not mean motor poles
hands down the best explanation of these switch types. clear and concise with great illustration. thank you!
Best explanation of poles and throws after visiting mutiple sources at the internet. Thank you sir!!!
Glad to hear it, thanks!
This is incredibly clear. One of the best I've seen related to circuit-related applications. Great job!
Better explained then my commercial lab teacher!
Nice, really high quality video
thank you so much sir love from india

Very clear, except that the positions were not explained. On-On vs On-Off-On, On-Off, etc. But maybe most got it anyway.
realy good explanation
Perfectly explained! Thank you so much for this!
Great video 👌 straight into my brain!!
Fantastic videos. Very clear and to the point. I watched a dozen videos all confusing me more on the subject. Thanks

Easy to under stand video. Some videos still leave you wondering.....and that's not what you want when you're dealing with electric.
great stuff. examples are key

Hi Ron,
May I ask you what is 832Y/480 ?
Does this stand for a three-phase transformer?
How else could you indicate?
Thanks so much
Sir show all pole and throw diagram connection all types of circute
Think I can power four items running on a double pull double switch?
Not at the same time. You could probably choose which two are on; but to have all four circuits on would require a 4 pole switch.
A double throw single throw switch in a bathroom for fan and light. Why are 2 poles needed. Why not 1 pole supplying both devices ???
Hi, thanks for your question:
Electrically, 2 poles aren’t needed (assuming the switch contact can handle carrying the current required to run both devices).
There may be other application restrictions (i.e. proximity of the fan & light) or building codes that require this be done with 2 poles.

please can you help a noob, can somebody tell me if i can wire a 3 pole
relay as a single pole, i think thats what i want/need?, i needed a
relay to turn on and off from - 24vac,on the coil side-, 240v 35a on the
main load , and with out spending silly money i could only find a 3
pole one cheap, thats 35 amps , all i need it to do is when activated by
the 24v ac , allow the current of my 240v ac to pass to make the
circuit, and that can be just the live or the live and neutral, etc etc
if
it can be done?, would wiring it so my live splits and goes in to all 3
poles and then out all 3 poles(when activated), to give more current,
as its for my mig welder ,(24v trigger), so more amps the better, thank
you
If I read it correctly you want a 1 phase to be used as a 3 phase?
That can't be done as the phases are 120 degrees seperated in the sinus wave.
1 phase keeps being 1 phase of 230v
It never goes to 380V
Nor will it increase your amps, if you got 16 amps at the start it can only remain at 16 amps.
If you got 1 liter of water, it will still be 1 liter even after you used 300 cups to poor it in.
What you start with is what you end with.
