摘要：
An electronic proximity switch employs two oscillators coupled through two electrical paths, one associated with an antenna serving as a proximity switch sensor. Absorption by an object near the antenna changes the coupling between the oscillators producing a dramatic phase shift that may be detected and used for switching purposes.
