Here for those no idea where tap a neutral wire for the timer.

Original is just 1 switch with no neutral in my storeroom. I modify it to 2 switch with a timer beside and take the neutral wire from the light. As you see the trunking running to the light. The light and switch is for outside backyard light. If locate at hall, don't use this way. The trunking freaking ugly. He.....

Those who wants to operate two electrical appliances one after another at different timing.  Especially playing 2 amplifiers alternately in the bird house.
