Failure analysis of reed switch:

The reasons for the failure of reed switches may include the following:

Wear or breakage of spring leaf: Long term use or frequent switching may cause wear or breakage of the spring leaf of the dry spring switch, thereby affecting its normal operation.

Poor contact: The contact points of the reed switch may experience poor contact due to dust, pollution, or oxidation, resulting in signal transmission obstruction.

External material interference: Dust, grease, or other external substances may enter the interior of the switch, interfere with the spring gap, and affect the performance of the switch.

Electromagnetic interference: External electromagnetic interference may cause false triggering or loss of sensitivity of reed switches.

Abnormal action process: Too fast or too slow action process may cause the reed switch to fail to complete the closing or opening operation normally.

To accurately analyze the failure of the reed switch, it is recommended to follow these steps:

Check the appearance of the reed switch for any obvious damage or looseness.

Clean the spring and contact points of the switch to ensure there are no contamination or oxidation issues.

Test the operational performance of the switch and observe whether there are any abnormal operating processes.

Eliminate possible sources of electromagnetic interference and ensure that the switch operates under suitable environmental conditions.

If the problem cannot be fixed, it may be necessary to replace the reed switch or seek the help of professional technicians.
