Installation and Usage Guidelines
When installing, the switch must be mounted on a flat surface and fastened with a flat washer or spring washer to prevent malfunction or casing damage caused by uneven surfaces. Choose models based on the environment: for humid or dusty conditions, it is recommended to use a sealed custom version to enhance protection. Do not apply lubricating oil to the button or actuator to prevent contact sticking, functional failures, or even burnout. During storage, keep the product in a dry, ventilated area, protected from rain or snow, and avoid high temperature and humidity that may cause component aging, ensuring the product retains its original performance.
