  1. This is helpful for those who have no basic knowledge in electrical, your instruction is easy to follow. Pls. keep posting.<br /><br /><a href="http://www.woertz.ch/&quot; rel="nofollow">woertz</a><br />

  2. Thanks admin for this wonderful post, full of ideas about electrical. The post is written in very a good manner and it entails many useful information for me. I appreciated what you have done here. <br /><a href="http://www.electricalserviceteam.com&quot; title="" rel="nofollow">Electrical Services</a><br />

  3. Thanks..

  4. i am unable to get the application of series and parallel lamp switch..

  5. Really i too why one should use this parellel combination manes..<br />

  6. Hi! My old house had a light switch arrangement that still has me curious about its workings! Perhaps you can illuminate us with a schematic and/or explanation!<br /><br />We had a light above the stairs, with a switch upstairs, and a switch downstairs. Either switch, when flipped, no matter whether the light was on or off, would turn the light on if it was off, and off if it was on. Can you

    • Sounds to me like you have incorrect polarity. Using a very basic example, it means you negative and positive are the wrong way around. (Negative to positive and positive to negative). Try looking at your switches and make sure the live goes to live and the negative goes to negative. Hope this helps.

    • What you’re describing is a simple 3 way circuit. Nothing wrong with it at all. It requires a special kind of switch and a “traveler” wire between the two of them to work.

      Note that it is NOT a parallel or series circuit. It is a 3 way circuit.

  7. i need design of my newly construct room with singly phase required connections as below:<br /><br />main panel contain 1 Fan Switch , 3 Bulb Switch 3 different points, at least 4 sockets required on main panel.<br /><br />2nd panel required for my Computer containing 6 sockets with 2 switches.<br /><br />3rd for electrical iron.<br /><br />kindly suggest me the basics of electrical wiring or

  8. I think it only for concept building otherwise no use of this circuit configuration


  10. what happen if we switch on both switches at a time

  11. what will happen if the two switches are in ON state

  12. Why we use 2 switch’s for a single bulb

  13. it does not happen ….

  14. why we use here 2 spst switch

  15. I have an overhead ceiling mounted light fixture in my hallway. I have a switch on one of the ends of the hall that I use to turn the light on and off with. The other light switch on the other end of the hall does nothing. I would like to have the capability to turn the light on and off using both switches if I need to. Both switches were wired to do that when house was built
    I would also like to turn the light on with one switch and turn it off with the other switch. Any ideas?


  16. I have a 3 phase pump mtr powered by an inverter that converts single phase 220 into 3 phase. the 220 to the inverter is controlled by an irrigation timer that sends 24vac to a relay which gives power to the inverter.
    I would like to add a second method for turning on the motor. This would be a pressure sensing circuit that would start the mtr through inverter when water pressure falls below a preset number.
    It could happen that the inverter would be running the pump when the timer clicked on. This would mean two parallel “switches” would both be on. The switches in this case would be two dpst relays each controlled by their separate sensing device (time clock/pressure switch)and separate coil voltage sources. The 220 power source would be the same mains power.
    This seems right to me. Am I missing something?Naturally the hot legs must not cross…or kaboom.

  17. So if one switch is closed, the other is effectively useless?

  18. I can definitely see why you would want to set up a parallel system with AC power and some switches. It seems like such a simple system could could be expanded upon to create a much more intricate service. I can see this functioning to power a something as large as a city grid.

  19. very good explanation

  20. Thank you for this explanation. This is helpful for my use case where i would want to add a smart switch for a bulb but would want the bulb to turn on either with the smart switch or with the physical switch. however, i would turn off only when both are off.

    Could you confirm that this would not have any impact if both the switches are on and ideally the result would be the same as if either one was on.?

  21. where we use switches in parallel and where we can use switches in series and its benefit
