Elevator Door Position Switches are generally used in elevator cars and shafts, including the top, bottom, and shaft walls of the car. It is crucial in the process of starting, running, stopping, and troubleshooting of elevators, ensuring the safety of elevator operation. This type of Door Closing Switch is used to limit the position or stroke of mechanical movement, causing the moving machinery to automatically stop, move in reverse, change speed, or move back and forth according to a certain position or stroke.
Door Control Switches are widely used in various machine tools and lifting machinery to control their travel and provide terminal limit protection. In the control circuit of the elevator, Door Limit Switches are also used to control the speed of opening and closing the car door, the limit of automatic door opening and closing, and the upper and lower limit protection of the car.
