Looking for a type of switch Answered
Hi People of Instructables!
I hope I am posting in the right place.
I am looking for a switch that when you walk pass a point it shuts off and when you walk the other way past that point goes back on.
For example... I have a flash-light in my hand, when I walk through a doorway into a house the light turns off. I go through the doorway the other way (to the outside) the light turns on.
It has to be able to do this through cloth as the flashlight could be in my pocket.
It can only work when you walk through the doorway but not when standing near the doorway
Does anything like this exist? if yes what is it called?
I have been searching the 'net and not been successful as I don't have a clue what I am looking for.
Any help would be greatly appreciated.
Thanks for reading my post!
