When the pit down final limit switch is actuated, what happens to the car?

When the pit down final limit switch is actuated, the car will not run at all. This switch is designed as a safety mechanism that ensures the elevator car does not descend beyond its designated lowest point, known as the pit. When this switch is triggered, it interrupts the circuit that powers the elevator's motor, effectively stopping any downward movement and preventing the car from operating further.

This safety feature is crucial in preventing potential damage to the elevator or creating unsafe conditions for passengers, as it halts the car's operation before reaching an area where it could become misaligned or encounter mechanical failure. In essence, the activation of the pit down final limit switch acts as a safeguard, ensuring that the elevator remains within a safe operational range.
