MikeN Posted September 25, 2022 Share Posted September 25, 2022 Currently to turn on/off the bedroom light I have to get out of bed, I want to enable switching off the bedroom light from the bed with a switch either side of the headboard and at the door. Elsewhere I would need 2 3way and a 4way switch as in the diagram : sparky says "mai dai, mai mee"....looking through Thai watsadu website I found that 3 way switches (common,L1,L2 terminals) are called 2 way here. I assumed that would make 4 way switches 3 way but I cannot find anything listed at Homepro, Dohome or Thai Watsadu. Only one way or two way. Are "4 way" switches not available here ?

AsianAtHeart Posted September 25, 2022 Share Posted September 25, 2022 Officially, a "4-way" switch is called a "double-pole, double-throw" switch. You might try looking for something along those lines. I would think Thai Watsadu should have them, but I don't know. They do have more variety than some of the others. I've never actually purchased one in Thailand--but have installed them elsewhere. Yes, you definitely need a 4-way for any switch in the line sandwiched between two 3-way switches. You can use as many 4-ways as you like, but you will also need to have three wires running between them (two hots plus neutral), instead of just the hot and neutral for a normal circuit--unless you are creative with the neutral line. There are always two ways to wire a light: Power to the switch, or power to the light. The former is best, as when the switch is off, you won't risk electrocution to work with the wiring at the light. In the case of two or more switches, the power must enter at one of the 3-way switches, with the light connected at the other one. Link to comment Share on other sites More sharing options...

Zaphod Posted September 26, 2022 Share Posted September 26, 2022 Smart bulbs, a smart speaker (i.e.: Amazon Alexa) and turn them on and off with a voice command. No wiring needed. 1 Link to comment Share on other sites More sharing options...
sometimewoodworker Posted September 26, 2022 Share Posted September 26, 2022 11 hours ago, MikeN said: Are "4 way" switches not available here The problem you are having is in the name and looking in the wrong place. You need to go to an actual electrical supply shop and discover the way a Thai will name them, then you will find them either in stock or available to order. The problem with looking in places like Homepro, Dohome or Thai Watsadu is that they carry the small percentage of items that make up 98% of the stuff people need and don’t bother with the 2% that few people want, and few Thai sparkies understand how to use. 2 Link to comment Share on other sites More sharing options...

OneMoreFarang Posted September 28, 2022 Share Posted September 28, 2022 You could use smart switches and relays. With those you could have 10 or more switches for the same light bulb. Home - Shelly Cloud Link to comment Share on other sites More sharing options...

Home - Shelly Cloud Well yes and also if one went to a system like cbus from clipsal at a rather hefty cost, one could have even more. Up to 256 addressable switches per relay or even more with some software haggling. Link to comment Share on other sites More sharing options...

That software is free, and all runs local - no big brother is watching. 1 Link to comment Share on other sites More sharing options...

bluejets Posted October 4, 2022 Share Posted October 4, 2022 Something about the "cheap" would be of concern I'd imagine. Plenty of insurance....??? mmm...maybe of no help considering the use of possible non-compliant equipment. As they say, the bitter taste of poor quality remains long after the sweetness of cheap price is forgotten. Link to comment Share on other sites More sharing options...

Very applicable, and it's a saying I'd always loved in the past, but had forgotten about, and I remember thinking it was very similar to a quote from the English philosopher, John Ruskin. So very true though. Link to comment Share on other sites More sharing options...
