ok so if you want control 1000w lighting? what you do?
i used one of this (livolo) switches before, its really 2 wire and don not need neutral(or negative) and picture is for 2 gang key. 4 point is line in. out 1 out 2 and com(ground) or( earth) that no need to connect to switch work. i try...
ok tanx. but what i do with neutral absence, and i dont think it be dangrous as you say.
please check out this link and tell me what you think they do?

Installation is as same as normal light switch, so does not require Negative line; Replace...
I design before this system with MOSFET and OpAmp and relay but just for 500 to 1000watt max. its something like 2 wire electronic switch (LIVOLO) if you have seen them before,
but i have 2200watt load. and that circuit was complicates really.
so i have acquaintance with this types of circuit...
Look. i need the circuit give me 5 volt and 300 mA when the load is ON. i use this circuit to keep my system alive. my wireless receiver, so i can send the command to turn the pump off.
Ok, of course i have full responsiblity of circuit and all consequence is just with and for me!!
and if you think triac is better so i can use it instead of relay.
OK! so the triac has no rule to providing current and voltage when the load is ON its just a switch like a relay but with low current. is that right?
and..... yesss, confirmed . we discussing about the load ON times. when its OFF any power supply will be work. we need the power supply for...
Yes . i don not use mechanical switch any more. and power circuit with load current when the load is ON. and in OFF time its simple to run it. if need i can use relay to ON-OFF load.
yes yes. i know that. thats the reason i told i use a switching power while the load is OFF to running the pump
(turn it on) then for turning it OFF using your method to keep the power of circuit to be able recieve command to off the pump,
yes look i have an ordinary RF transmitter and in switch i have receiver and a relay but if i use triac i dont need relay any more, my RF receiver need 5 volt and about 200 mA current power supply and i hope i can use your method to power my circuit. and on-off my switch and water pump remotely...
