Elevator Limit Switch Function:
The main function of the elevator limit switch is to ensure that the elevator stops when it reaches a floor and to safely halt it in emergencies.
Elevator limit switches play a crucial role in the elevator system. They are typically installed at the top and bottom of the elevator shaft as essential safety devices. When the elevator car encounters the limit switch, it immediately stops operating to prevent further ascent or descent. This mechanism consists of several layers: first, there are the upper (lower) limit switches, which stop the elevator from moving up (or down) when activated; next, there are the extreme limit switches that cut off the control circuit entirely, making it impossible for the elevator to operate until external intervention occurs. This design ensures safe operation under various circumstances, preventing accidents caused by equipment failures or operational errors.
Additionally, elevator limit switches are used to control the speed of the elevator doors and to limit the automatic opening and closing of the doors, as well as to provide upper and lower limit protection for the car. These functions work together to ensure the safe and smooth operation of the elevator, safeguarding passenger safety.
