HENGDA Limit Switch HD-1370-J is a type of travel switch primarily used for travel control and limit protection in elevators and similar equipment. When elevator moving components reach a preset position (such as upper or lower limit points), the switch is triggered through mechanical contact, causing the contacts to actuate and switch the circuit. This allows the elevator to stop, reverse, or change speed, ensuring it operates within a safe range and preventing collisions or overrun accidents. Please contact customer service for more information.
