To illustrate the door bell that I was referring earlier... I wonder why there are 4 holes?? Upon closer check, every 2 holes at the bottom and at the top connecting to the same copper plate in it... [attachmentid=3755235] [attachmentid=3755236]

Then what kind of door bell is not configured through neutral completing circuit?

But I just wonder why my friend house has been using this too for ages... Same model, as door bell at outdoor?

So this 240v will be sufficient to kill a person? Sorry ah side way a bit... I also saw those outdoor switches...Will it be safe then? I have some at the side 

So my switch above can pass thru standard voltage? In another words, both door bell button and door bell I got are rather alien here? I got them when I went Taiwan 

I have then bought a Legrand-branded one with built-in transformer

I have learnt the hard way... Spent extra unnecessary... LoL!

Just wonder if I can actually add the transformer like 12V one to this 220v doorbell and this 220v door bell will still work?

Here you go...
Conversion from 4-wires type to 2-wires type doorbell.
No major modification needed. Just add one terminal block connector.



Please take note of this type of doorbell design weakness!
If your doorbell switch located at outdoor and exposed to rain water, make sure you use the outdoor rated switch.
Non-outdoor rated switch will give you headache due to short circuit caused by water.
Short circuit will lead to nuisance MCB tripping.

Yup, this door bell I actually bought from Thailand. I buy this door bell mainly of the brand name and sound i like BUT very unfortunately you guy mentioned this is not suitable for outdoor. If u go to Schneider Malaysia website you may found they sell the weatherproof door bell switch BUT just cannot find this door bell sell in their Malaysia website.

I found this outdoor enclosure box for doorbell switch at lelong.com.my.
If you really like it, just go ahead install your doorbell. Ensure proper weather sealing for the switch.

You can't add step-down transformer to a doorbell system that required AC 240V as input power source.
Just buy the weatherproof switch to solve your problem.

How about a step down transformer plus a relay? Will it work?

Speaking of weatheproof switch and it's a bit off topic but just to ask if anyone installed outdoor switch sockets?

Yes, I have 2 3point plug socket outside but not exposed, currently have weatherproof cover-the plastic type. I believe one socket is for the future mini water feature outdoors. But don't know why need one more 3 point plug socket.

After seeing the concerns over weatherpoof cover etc, makes me wonder whether I should ensure extra protection.

I have a doorbell switch under Pieno range by schneider but not sure if also need to have cover?

Door Bell is 10A 250V. That link you provided looks solid but need transformer right?

The 3 point plug socket is 13A 250V

240v is dangerous but switch is not 240v, we based it on 6A. power socket is 20A. Hence, 6A is like ant bite

You looking for unusual fetish. Where to get? 😝

Suggest to you to use some prerecord audio electronics board. Put a switch and you can use it.
