Abstract:
1. A non-contact touch switch, utilizing a human body as an inductive medium to enable a control circuit to accurately switch an AC power source comprising: an outer cover with an inner side disposed at an outlet of the AC power source; a microcomputer control circuit disposed on an inner side of said outer cover; a medium transferring interface being disposed on said outer cover, providing a non-conductive substrate and an etched circuit board attached to said non-conductive substrate to and being connected internally to said microcomputer control circuit; a start switch being attached to said circuit board, having two ends with one of the ends being connected to said microcomputer control circuit, and another one of the ends providing a control contact connected to said AC power source so as to control electrifying time of an electrical device electrically connected to said outlet; and a power interceptor being disposed at the circuit board between and connected to said microcomputer control circuit and said control contact to intercept, rectify, and stabilize an external power supply directly as a useful internal power supply through said AC power source such that the non-contact touch switch is capable of being free from an additional battery to perform a normal work once said external power supply is connected.
