8536.50.90.55 - Limit

This HTS classification covers "Limit" switches, which are a specific type of electrical switch designed to detect the presence or absence of an object, or to indicate a specific position of a mechanical component. These switches typically operate by being physically actuated when a moving part comes into contact with their lever, roller, or plunger. They are commonly used in automation, industrial machinery, and control systems to signal end-of-travel, position detection, or to control sequences based on physical constraints.

Within the broader category of "Other switches," this classification is distinguished from sibling categories such as rotary, push-button, snap-action, knife, and slide switches by its mechanism of actuation and primary function. While other switches are operated manually or by general electrical signals, limit switches are specifically designed for mechanical actuation by physical contact with an object or component, triggering an electrical signal upon reaching a defined limit or position.

As this is a leaf node within the HTS structure, there are no further subcategories under 8536.50.90.55. Therefore, classification within this code relies on accurately identifying the item as a mechanically actuated electrical switch intended for position or limit detection. Examples include microswitches with levers used in conveyor belt systems to detect jams, or switches integrated into robotic arms to signal the end of their movement range.
