Limit switches, both Normally Closed (N/C) and Normally Open (N/O), are crucial safety components in elevator systems, regulating and monitoring the movement of the elevator car. These specialized switches are strategically positioned along the elevator shaft to define specific points, setting limits for the travel distance and ensuring safe operation.

The Normally Closed (N/C) limit switch acts as a safety measure, interrupting the elevator's movement when activated. It typically triggers when the elevator reaches predetermined positions, signaling the system to halt, preventing the car from exceeding safe limits or traveling beyond the designated floors.

Conversely, the Normally Open (N/O) limit switch operates differently, allowing the elevator to function within its normal parameters. When activated, it can signal the system that the elevator has reached a certain level or position, enabling the proper functioning of specific elevator components or confirming the elevator's alignment.

Both N/C and N/O limit switches are integral in maintaining the elevator's safety and preventing potential accidents by ensuring that the elevator operates within predetermined parameters. These switches undergo rigorous testing and are designed to comply with stringent safety standards, providing reliability and accuracy in their functionality.

Regular inspection, maintenance, and calibration of these limit switches are essential to guarantee their proper operation and adherence to safety protocols, ultimately contributing to the safe and efficient functioning of the elevator system.

In summary, N/C and N/O limit switches are vital safety features within elevator systems, playing a pivotal role in regulating the elevator's movement, ensuring passenger safety, and preventing potential hazards during operation.
