Claim Text:
1. A microcontroller based electronic switch for detecting an external motion signal, comprising: a controllable switching element, electrically connected between a load and a power source; a detection means, for detecting an external motion signal played by an user and convert said external motion signal into a message carrying sensing signal; and a microcontroller with program codes to read and interpret the message carrying sensing signal generated by the detection means; wherein said microcontroller is electrically connected between said controllable switching element and said detection means, said microcontroller controls a conduction or cutoff state of said controllable switching element according to said message carrying sensing signal(s) generated by said detection means; wherein when said controllable switching element is in the conduction state, said microcontroller further controls electric power transmission level from the power source to the load according to a signal format of said message carrying sensing signal received from said detection means; wherein the detection means is a touchless interface forming a defined detecting zone for detecting a motion of an object entering and leaving said defined detecting zone; a circuitry responsively generates a first voltage sensing signal with a time length corresponding to a time interval of the object entering and staying in said defined detecting zone; when the object leaves said defined detecting zone, the detection means delivers a second voltage signal.
