It is usually composed of a thin metal or plastic pin located on the top or side of the switch. When an external force acts on the ejector pin, it triggers the action of the switch, thereby changing the state of the switch (usually open or closed). This structure is commonly used in various automatic control systems, safety devices and sensors to detect the position, movement or touch of an object.

[0003] In order to ensure the accuracy of positioning the material sheet and ensure correct detection, it is necessary to add a spring during positioning to reduce the pressure during positioning.
