1results about How to "High trigger sensitivity" patented technology

This utility model discloses a high-precision digital sensor keypad switch keyboard, characterized by: including a PCB board, on which at least one digital magnetic sensor keypad switch is disposed; and on which a digital magnetic sensor is disposed, capable of linearly and accurately detecting the change in magnetic flux in the Z-axis direction caused by the height difference of the permanent magnet within the keypad switch, and quantifying it into a digital sample value to generate a high or low level digital signal output. The digital magnetic sensor and the keypad switch are configured in a one-to-one correspondence. The purpose of this utility model is to overcome the shortcomings of the prior art and provide a digital magnetic sensor keypad switch keyboard with a simple structure, low cost, effectively reducing the wobbling amplitude during the keypad's movement stroke, high triggering accuracy and reliability, relatively low frictional resistance, good tactile feel, and ultra-low latency.
