Introduction
The core functions of smart security devices such as door lock magnetic detection, signal transmission in security alarm systems, and switch triggering of window and door sensors all rely on the support of micro switches. Security devices cannot afford a single false alarm or missed alarm. The precise triggering and reliability of micro switches lay a solid foundation for the reliability of security systems.
The core function of the micro switch
Micro switches adapted for security scenarios are designed with "low power consumption + high sensitivity". Their static power consumption is reduced to the microampere level, meeting the long-term usage requirements of battery-powered devices. The trigger stroke is controlled within 0.1-0.2mm, enabling precise detection of the slight movements of door and window openings and closings, and avoiding missed alarms due to insensitive triggering. In smart door locks, micro switches are responsible for detecting whether the door is fully closed. Only when the lock is confirmed to be in place will the locking signal be triggered, preventing the safety hazards caused by "false locking". In window and door sensors, they quickly send signals to the alarm host by sensing changes in the gaps between doors and windows, with a response time of no more than 0.1 seconds.
Conclusion
Data from a security equipment manufacturer shows that the false alarm rate of window and door sensors equipped with high-quality micro switches has dropped from 7% to 0.8%, and their service life has been extended from 3 years to over 6 years. Currently, domestic micro switches have been widely applied in various devices for home security, commercial security, etc. With stable performance and affordable prices, they have become the mainstream choice in the security industry, providing basic security guarantees for both home and commercial environments.
