Introduction

As an indispensable trigger "sentinel" in various electronic devices, industrial machinery and even household appliances, micro switches, despite their small size, play a crucial role. Its sensitivity and reliability directly affect the overall performance of the equipment. Mastering the correct usage norms is the foundation for ensuring the long-term safe operation of the equipment.
Core precautions
Before use, be sure to read the product manual carefully to clarify the key parameters such as the contact structure of the switch (normally open/normally closed), rated current and voltage, operating force, and stroke. Incorrect matching will lead to switch failure or equipment damage. The pressing or releasing action should be smooth to avoid violent impact or excessive pressure that may damage the internal reed. Ensure that the drive rod can be fully pressed down to the action point and reset. Insufficient travel can easily cause poor contact or adhesion of the contacts. The switch body must be installed stably, and the driving mechanism (buttons, levers, etc.) must be precisely aligned with the force application point to prevent additional stress or action jamming caused by skewing. It is strictly prohibited to allow the switch contacts to carry current or voltage exceeding their rated values. Overload is a common cause of contact ablation, adhesion and even fire. Inductive loads (such as relays and motors) need to be equipped with additional arc extinguishing circuits. In dusty, damp or oily environments, the sealing model corresponding to the protection level (such as IP67) should be selected, or a protective cover should be installed on the switch to prevent contaminants from entering and causing oxidation or short circuits of the contacts. In a continuously vibrating environment, anti-vibration structural designs should be selected or additional shock absorption measures should be taken to prevent misoperation or loosening of internal parts. For frequently used micro switches, it is necessary to regularly check the wear of the contacts, whether the operation is smooth and if there is any abnormal noise. If any abnormality is found (such as increased contact resistance or sluggish action), it should be replaced in time.
Conclusion
The reliable operation of micro switches relies on a clear understanding of specifications, meticulous and standardized installation, strict control of loads, effective environmental protection, and regular maintenance and inspection. Following these seemingly minor operational points is precisely the key to ensuring the overall safety, stability and longevity of the equipment. Only by paying close attention to every "slight movement" can one achieve the "great feat" of ensuring the long-term reliability of the equipment.
