What is the purpose of a car top switch in elevators?

The purpose of a car top switch in elevators is to cut power for safe maintenance access. This switch is typically located on the top of the elevator car and serves as a critical safety feature. When activated, it disconnects the power supply to the elevator system, ensuring that maintenance personnel can safely perform inspections or repairs without the risk of the elevator moving unexpectedly.

This safety mechanism is vital in ensuring the well-being of technicians working on or near the elevator, as it prevents accidents that could occur from unintended elevator movement. By providing a means to safely lock out power, the car top switch plays a key role in maintaining a safe working environment during maintenance procedures.
