What is the function of a micro switch in an aircraft system?

The function of a micro switch in an aircraft system is not primarily about being a remotely located switch that cannot be directly activated from the cockpit. Micro switches are critical components that are designed to be highly sensitive and are often used to detect specific changes in position or pressure within the aircraft systems.

Their key role typically involves serving as limit switches that activate or deactivate systems based on the position of mechanical parts. For instance, they might be employed in landing gear systems to confirm that the gear is fully extended or retracted, ensuring that the aircraft's safety mechanisms are operational.

In this context, a micro switch can indeed be operated indirectly by other mechanisms that are controlled from the cockpit, making it important for monitoring and controlling various functions without requiring direct activation from cockpit switches. This precision makes micro switches vital for maintaining safety and performance in aircraft operations.
