Title:
MAGNETIC SWITCH HAVING FILTERING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2023/216578
Kind Code:
A1
Abstract:
The present application discloses a magnetic switch having a filtering function. The magnetic switch comprises: a magnetic sensing module and a specific integrated circuit; the specific integrated circuit comprises a power supply module, a comparison module, a filtering module, and a logic operation module; an output end of the magnetic sensing module is electrically connected to an input end of the comparison module; the filtering module is electrically connected between an output end of the comparison module and an input end of the logic operation module; or, the filtering module is electrically connected between the output end of the magnetic sensing module and the input end of the comparison module, and the output end of the comparison module is electrically connected to the input end of the logic operation module. The present application provides a high-integration magnetic switch which has high frequency response, not only has the characteristics of a conventional magnetic switch, but also can set a switching frequency threshold by means of the filtering module, such that the high-integration magnetic switch can output high and low level change signals within a set switching frequency range. Therefore, the present application avoids the effect of invalid action of the magnetic switch under the effect of a vibration environment and other environments, and also reduces the power consumption and costs.
