Simple Stair case timer working and connection diagram explaining new 

Hy sir I have one doubt how check this timer is complaint or no complaints Al ways on all lights

This is great !! thanks.. What is the timer that you are using?

I want you example to me 10 press bottom switch. 1 timer ২ bulve wringing. Diagram.

Can you help/guide with an contractors who can do this for a building in Mumbai India

Thanks. Still weird. Because mine work a bit different:) I connect pin number three to a "lamp spring switch" 3's pin-L goes to a switch( with a lamp) and closed with N. Whenever I push the button it will break the circuit on pin 3 and this will fire the pin number four to turn on the lamps. In your example you put a constant L phase to pin number 3. And whenever you push the button, it will open the circuit, and L phase will reach the pin number 3. So my main question is this. What does pin number 3 is for? It has a constant phase-L? Or it should receive L Phase to trigger the pin number four??? It fires on a break of a circuit, or on the connection of the circuit??? Mine works exactly the opposite nof what is being shown in this video:-)

Same bell push. Switch

Sir please let me in hindi language
