Making a switch
Hi all,
I need some advise on circuitry. I'm trying to create a circuit in which opening a set of contacts will turn on an LED light. For reference i am using a button cell, but will be upgrading to a AAA or AA battery when i get the mechanics right.
I have a few ideas, but nothing that wouldn't require many days of tinkering with a soldering iron and circuit board.
Does anyone have any ideas on how i might be able to do this?
Cheers
