The current would be in the microamp range if a LED was used as a mains tester.

Consider the following :-
 

 

 

A much safer method for test screwdrivers is to drive a LED with a battery and detect mains voltage with a sensitive transistor circuit.

 

 

Will microamps drive an LED  directly as your circuit implies, 0.44mA?

You are wrong that LEDs are not used in the test screwdrivers 

Though they do require batteries. The green is from touching both ends, the green has and red shows an active line socket.

So the ways they detect are slightly different.

Of course. Note the batteries. Sure it can be done, but the cheapest, most common, and most reliable are the simple neon light and current limit resistor. This type a has been around for many decades.

If the voltage is enough to light neon then it's likely to be enough to hurt you. The electronic led versions can sense lower voltages though.

What do the LED sense of the cells are dead? No light means no voltage? I wouldn't trust it.

Also, I dislike renewing batteries every time I want to use something. I fail to see the advantage.

But...

If ASEAN stuck to Thai news only, I doubt there would be many people reading it.

 

Monk embezzles 3 million baht, and elopes with a 14 yo from Korat. What's new?

Agreed. I don't even glance at postings about Thai people killing and being killed by each other. They don't care and I stopped caring years ago.

likewise, foreigners killing or being killed. Same old same old.

How can it be 'news' when it happens 50 times a day?

At least they are telling you its out of stock. 

 

More annoying than that, is ordering something...  (i.e. before Christmas or before a trip etc)... then looking again a few weeks later to find out the order has been cancelled by the vendor a week ago and its now too late to order from elsewhere.

...  This has happened to me a number of times now...      

 

Another one is the 'bait and switch'... With a supplier cancelling the order... but 'other vendors' have the exactly the same item (exactly the same photos) for a higher price and it becomes obvious they are gaming the system.

Totally agree. I've complained about this to lazada. It's happened to me four times in the last month.

They promise to deliver hoping they can stock it in time to ship to you but when they can't either they or lazada cancel.

Stores stock as little as possible taking a gamble with my time and lose nothing when they cancel. Lazada should fine them if they do this repeatedly.

And yes the same vendor floods the site with many stores using slightly different names while being clearly the same store. I have to wade thru them to find an actual valid competitor.

Personally I think it's all down to slower delivery from China. It's becoming more difficult to find vendors who don't ship from China. For many items one has no choice.

There is no neutral in light switches!

Very observant.

Double throw switches SPDT do however have a single pole contact. They are not interchangeable like SPST switches.

Those are labels of the wires connected to the switch. As in Line and Neutral.

You know...those voltage things.

Almost all my tools are 18V Bosch, including an angle grinder, a SDS Hammer (GBH 18V-26 F) and a circular saw. At least for all the work which I did until now they have enough power, and I was/am surprised for how long the batteries last before I have to recharge them.

The only mains power "tool" which I bought was a Festool dust extractor.

I would buy them all again, they work great. 

 

When I was chopping out gobs of concrete around my pool plumbing to get at a leaking pipe ( I note that pvc plumbing requires solvent welded joints everywhere in the world except the Kingdom apparently) I used my hammer drill for hours. I'm sure I'd go thru several charge cycles with batteries. On the other hand that would have forced me to rest more than I did.

Certainly the newer lithium cells, principally lithium iron phosphate LiFePo are so much better that the first battery tools that used nickle metal hydride or heaven forbid, cadmium cells.

In general things like Sabre saws, drills, maybe even circular saws for light work are the way to go for battery tools.

 I used to do a lot of ripping on oak with my radial arm saw and so battery tools wouldn't work for that. But they are so convenient to use outside.

I must say however that where your Li cells come from can make a big difference. Cheap cells are not only junk but they are dangerous to use.

BTW,are you aware that if you store your tools for a while discharge the Li cells to approximately 30% charge. It will improve battery life. And don't let them freeze; yeah, like that will a problem here!

That is why you, as a neophyte, should use more than 1 test device, if you add a 30 baht neon screwdriver (I know it’s probably an LED now) then it will light up, even though your meter shows nothing. The other thing you should do is wear safety 😉 filopflops and if possible keep one hand in your pocket. Both of these precautions will be enough to probably reduce a shock to a minor disturbance and as long as it doesn’t cause you to fall off the ladder you will continue to live a long time. I can’t remember how many shocks I have got, probably single or low double digits, & maybe even none in Thailand, but every one was an uncomfortable reminder that I probably hadn’t followed my own advice not to touch the bitty bits.

Neon is still used for those detectors because the ionization voltage is about 95V but current is micro amps. So even it's capacitive coupling only that allows such current to flow literary through your body to grounded.

 LED currents are generally in at least the milliamp range. To light one of those would require much more body capacitance and this be dangerous, about a thousand times more current than neon needs to ionize.

Thanks, I believe you, I like to learn.

 

Edited:

I was thinking what happens if one wire is longer, would that cause the 50hz to not osculate at the same time? Just wondering if both Lines would be in sync. I can see no problem with DC like you said for PC circuit boards, just curious,

In general even connecting Line from two different breakers is OK since for houses since only a single phase comes in to the load center so all subsequent circuits will be in phase.  It is not recommended practice though.

Although load power factor may change each branch circuit  phase very slightly there is too small a difference to cause problems.

No, if you throw the switch on left you have two lives (line(s)) going to your light, not good.

Wrong. No current flow if light is connected to both line or neutral at the same time.

Of course both switches should be fed from the same breaker.

Current will only flow thru the light if one side is line and the other is neutral. Line to line or neutral to neutral there is no potential difference  so no current flow.

Check it out on the web about how double pole light circuits work.

Maybe Crossy will come along to convince you.

I spent over 55 years as an electronic computer circuit designer. I've also wired numerous switches this way. In DC circuits such an arrangement is used to switch polarity for reversing DC motors for instance.  Think about it more and you'll see it.

Change line and neutral to plus and minus and you'll see.

Good luck.

I bought most of my Bosch tools from this company. I have very good experience with them.

TCL TOOLS Sales & Services - Assembly of Perfection

Thanks. I'll check it out.

Asia retired EE I have grown watery of battery powered tools that just don't have the necessary power or deplete the batteries very quickly. I love my 20v DeWalt drill but for angle grinder and hammer drill I use good old 220vac.

Batteries Wil get better someday but they're not there yet. I spent a lot of my career studying battery tech and I'm still waiting.

Almost everyday there are breathless articles about some new battery development that  will change the world. I'm still waiting.

But if it works for you go for it. Portable power tools are sure convenient but short battery life and expensive battery replacement cost discourage me.

I think your talking about a "(X2) Single Pole, Double Throw" switches. If two switches control one light, and you have some flickering or one stays lit very dim you may have induction on one of the wires, usually half voltage, so around 110 with multi meter.

I cant comment on this since I can only do this wiring myself and only if I draw everything out on paper and label wires. There is a bunch of smarty pants on this forum though. :-)

Both top and bottom switches must the single pole double throw.

Inductance has absolutely nothing to do with it. There may be some leakage somewhere in the wiring or even capacitive coupling bit these would only allow minimum current that might partially light very low current devices.

My bet is that the switches are wrong. The two wires from the light go to the center poke on both switches. The two power wires go to the other two switch contacts. Draw a diagram and you'll see.

That is a very good reason.

I just counted in my head. I think over the last 3 years I bought 7 Bosch Power Tools. Good tools make work so much more enjoyable.

When a left America two months ago after going back to sell my house and cut my roots I left behind quite a few high quality tools and power tools. Too heavy to be worth shipping and 120VAC powered.

Profit ftom my house means I buy what I want now and I like good tools. The problem here is finding them because few people will pay for them here. So I stick to Bosch,  Makita, and DeWalt mainly.

Hand tools are a loss. I keep them until they rust apart in a year and then throw them away and buy more garbage from China. The only way to keep it is to wrap the tools in rags soaked with WD40.

How do the like the "stainless steel" so ubiquitous  here that turns brown in a month? If I'm shopping for anything stainless I take a magnet with me.
