Hello, everyone,

I want to understand how the NO NEUTRAL electronic timer switches and the NO NEUTRAL PIR motion sensor switches works. I would apreciate if someone can make this clear to me.
Thank you.
 
There are two ways of doing it.....some have a battery to operate the electronics and a relay, some rely on the lamp being in place, a tiny return current can then flow to neutral through the resistance of the lamp.
Are you an Angler wirepuller?
 
I note that you are an electricians mate? Have you asked the guy that you are a mate to? If I had a "lad" that was looking to me for information i would love to spend ages explaining things, that is just part of having someone who is helping you out. Can he not help you? I hate to think that someone in a responsible position cannot take the time to pass on knowledge.
 
I believe that they put a resister in parallel with the switch,
This resistance is chosen to allow a small current to flow,
this provides the power for the electronics.
 
never got the hang of this fishing lark, ever since the home made dynamite sticks fetched up nothing but scrap metal. anyway, can't see the point of catching something i can't eat. :oops:

The beauty of sea fishing is you get to eat a lot of your catch and it is fresher than any shop bought fish. from catch to table sometimes less than an hour. mmmmm.
