hi all. i want to create two circuits which are activated by their proximity to each other. i had thought of using a reed switch. this would allow me to use a magnet on circuit A to activate the switch in circuit B but the effect could not be mirrored because the magnet would activate whichever switch it it near. i dont want to make a physical connection because the circuits are separated by a non conductive material. can anyone think of how i might be able to accomplish this? thanks.
