Contactless switch and associated method

摘要

A contactless switch provided by the present disclosure is coupled to a signal input device and receives a magnetic signal generated by a magnetic trigger mechanism. The contactless switch includes: a magnetic sensor, for sensing the magnetic signal and generating a corresponding trigger control signal; a controller, for generating a switch signal according to the trigger control signal; and a mode switch module, for processing the input signal to generate an output signal according to the switch signal.

1. A contactless switch, coupled to an alternating current input power, comprising:
a magnetic trigger mechanism, for generating a magnetic signal according to a user trigger; a Hall effect sensor, for sensing said magnetic signal and generating a corresponding trigger control signal; a controller, for generating a switch signal according to said trigger control signal; a power switching module, for processing said alternating current input power to an output power according to said switch signal; and a power converter for converting said alternating current input power to an operating power of said controller; wherein said power converter is controlled by an awake/sleep cycle, said power converter outputs said operating power to said Hall effect sensor, said controller and said power switching module during an awake mode of said awake/sleep cycle, and said power converter does not output said operating power during a sleep mode of said awake/sleep.
