End switch
End switches, also known as limit switches or position switches, are electromechanical devices used to detect the presence or absence of an object, or to monitor the position of moving parts in industrial machinery.

End switches, also known as limit switches or position switches, are electromechanical devices used to detect the presence or absence of an object, or to monitor the position of moving parts in industrial machinery. These switches typically feature a mechanical actuator, such as a plunger, roller lever, or whisker, that operates a set of contacts when a predetermined position is reached. Common technical specifications include contact ratings (e.g., 10A at 250VAC), number of poles (e.g., 1NO/1NC, 2NO/2NC), degree of protection (e.g., IP67 for harsh environments), and mechanical life (e.g., 10 million operations). They are available in various configurations, including snap-action, slow-action, and maintained contact types, and can be fitted with accessories like cable glands or mounting brackets.
End switches are widely deployed in industrial automation, conveyor systems, packaging machinery, and material handling equipment. They are essential for safety interlocks, end-of-travel detection, and position feedback in robotic arms, elevators, and machine tools. In process industries, they monitor valve positions or gate openings, while in building automation, they control door and gate limits. Their robust design makes them suitable for dusty, wet, or explosive environments when properly rated.
Key subcategories within end switches include standard limit switches, miniature limit switches, and heavy-duty position switches. Common article codes often follow patterns like LS-XXXX or Z-XXXX, where the prefix indicates the series (e.g., LS for limit switch) and the suffix specifies actuator type, contact configuration, and enclosure material. For example, a code like LS-1A-2B might denote a standard switch with a roller lever actuator and 2NO/2NC contacts. Popular series include the Z-15G and D4N families, which offer modular designs for easy customization.
