Factory Price Adjustable Swivel Arm Electrical Micro Switch Elevator Travel Limit Switch For Lift Parts

The elevator limit switch is a safety device that limits the position of the elevator car when it reaches the top or bottom floor. It is used to prevent the elevator from continuing to move beyond the predetermined travel and avoid the dangerous situation of hitting the top or sinking to the bottom. The following is a detailed introduction:
Installation location
In the shaft
Upper limit switch: usually installed at the top of the shaft, a certain distance from the top leveling position, such as 150mm, as the highest limit protection when the elevator rises.
Lower limit switch: installed at the bottom of the shaft, a certain distance from the bottom leveling position, such as 150mm, to prevent the elevator from exceeding the specified minimum position when descending.
On the car: mainly used to detect whether the elevator car reaches the specified floor or area during the ascent or descent process.
Forced deceleration switch
Upper forced deceleration switch: installed in the elevator ascending path, the distance from the terminal leveling plug plate is calculated according to the rated elevator speed and special deceleration of the elevator, usually in the range of 150mm-500mm.
Lower forced deceleration switch: installed in the elevator descending path, the installation position is determined according to the rated elevator speed and special deceleration of the elevator.
