The proximity switch and logic processing circuitry employed in the present invention are known per se in the art, and those skilled in the art will understand which particular type is employed under the teachings of the present invention.
The proximity switch is a position switch which can be operated without mechanical direct contact with a moving part, and when the sensing surface of the object proximity switch reaches an action distance, the switch can be actuated without mechanical contact and any pressure. Inductive proximity switches are a type of proximity switch that utilizes a conductive object to generate eddy currents within the object when the object is in proximity to the proximity switch that generates an electromagnetic field. The eddy current is reacted to the proximity switch to change the internal circuit parameters of the switch, so as to identify whether a conductive object moves close and further control the on or off of the switch. Inductive proximity switches generally consist of three major parts: the circuit comprises an oscillator, a switching circuit and an amplifying output circuit.
The logic processing circuit comprises a voltage comparison circuit, wherein the voltage comparison circuit is a circuit for identifying and comparing input signals, and has the function of comparing the magnitude of the input voltage and giving out logic high and low level values according to the comparison result. The approach switch unit 6 outputs the logic state of the key switch by adopting a method of interval voltage comparison. When the proximity switch unit 6 detects the action of the key, the high-voltage side is converted into the low-voltage side by using the logic voltage comparison circuit, so that the logic level detection of the key is realized.
The proximity switch unit 6 in this embodiment is an inductive proximity switch, but other suitable types of proximity switches may be used.
