What is the limit switch box
A limit switch box is a device used to detect the position of moving objects. It is typically used in industrial environments to control the movement of machinery and equipment.
The limit switch box consists of a casing, a switch, and a control lever. The shell is usually made of metal or plastic to protect the button from damage. Controllers are usually reed switches or microswitches used to detect the position of the lever. Levers are usually made of metal or plastic and connected to moving objects.
When the moving object reaches the predetermined position, the joystick will move and activate the switch. Then, the switch will send a signal to the control system, which will take appropriate action.

Limit switch boxes are an important safety function in many industrial settings. They help prevent accidents by ensuring that machinery and equipment can only operate in safe conditions.
Here are some benefits of using limit switch boxes:
They can ensure that machinery and equipment can only operate in safe conditions, thereby helping to prevent accidents from occurring.
They can ensure operation only when needed, helping improve the efficiency of machinery and equipment.
They can help reduce maintenance costs by preventing damage to machinery and equipment.
They can help improve product quality by ensuring that products are produced only in safe and high-quality conditions.
If you are considering using limit switch boxes in industrial environments, it is important to choose the appropriate limit switch box according to your needs. You need to consider the type of machine or equipment you are using, the operating environment, and the safety requirements of the workplace.
setting
1. Move the valve to the closed position and adjust the upper cam so that the "close" switch has a signal output.
2. Move the valve to the open position and adjust the lower cam so that the "ON" switch has a signal output.
3. Run the valve switch several times to confirm the accuracy and reliability of the limit switch signal.
*Please remember that incorrect cam position settings will result in no signal output.
Reinstall the cover
*Carefully secure the switch box cover and do not damage the O-ring.
*Check the position indicator.
*Operate the actuator to the fully open/fully closed position and check
*Position indicator.
*If the position indicator is not properly aligned with the cover
*Align in the correct direction, then install the cover and tighten the screws on the cover.
Important safety regulations
*Before performing any maintenance, please cut off the power supply.
*please get in touch with us when replacing any parts.
