Abstract
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.
Claims6
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.
A method for controlling a contactless switch, the contactless switch being coupled to an input power, the method comprising:
- generating a magnetic signal according to a user trigger;
- sensing the magnetic signal by means of the Hall effect and generating a corresponding trigger control signal;
- generating a switch signal according to the trigger control signal;
- processing said alternating current input power to an output power according to said switch signal;
- converting said alternating current input power to an operating power;
- and
- controlling provision of the operating power according to an awake/sleep cycle;
- outputting said power switching module during an awake mode of said awake/sleep cycle;
- and said no operating power during a sleep mode of said awake/sleep.
