Question: 1 / 400

What type of switch is commonly used at the top and bottom of an elevator shaft to prevent the car from moving too far?

Safety switch

Limit switch

The type of switch commonly used at the top and bottom of an elevator shaft to prevent the car from moving too far is a limit switch. Limit switches are designed to detect the presence or position of an object and ensure that the elevator does not travel beyond its intended range. They serve as critical safety devices that stop the elevator from exceeding its travel limits, thereby protecting both the equipment and the safety of passengers.

In the context of elevator operation, limit switches help to ensure that the elevator car does not reach dangerous positions such as overtraveling the top or bottom of the shaft. By automatically cutting power to the elevator's drive system when these limits are reached, limit switches play a vital role in maintaining smooth and safe operation.
