Position switches

Position switches, also known as limit switches or travel switches, are electromechanical devices designed to detect the presence or absence of an object, or to monitor the position of moving parts in industrial machinery. These switches operate by physically contacting a target, typically a cam or actuator, which then opens or closes a set of electrical contacts. Key technical parameters include the number of poles (e.g., 1P, 2P), contact configuration (e.g., normally open NO, normally closed NC, or changeover SPDT), actuation type (e.g., plunger, roller lever, rod, or whisker), mechanical and electrical life ratings, and degree of protection (IP65, IP67, or IP69K for harsh environments). They are available in various housing materials such as metal, plastic, or stainless steel, and can be equipped with pre-wired cables or connector versions for quick installation.

Position switches are fundamental components in industrial automation, safety systems, and material handling applications. They are commonly installed in conveyor systems, packaging machinery, elevators, hoists, and robotic cells to detect end-of-travel, overtravel, or home positions. In safety circuits, they serve as interlock switches on guards and doors, ensuring machinery stops when access is required. They are also used in valve position monitoring, crane limit detection, and automotive assembly lines. Their robust design makes them suitable for dusty, wet, or high-vibration environments, such as in food processing, mining, and heavy manufacturing.

Our catalog includes a wide range of position switches, such as the AB1110 series with standard roller lever actuators, the AB1111 series with plunger actuators, and the AB1112 series with adjustable rod actuators. These models typically feature a 1P or 2P contact block, with electrical ratings from 10A to 16A at 250VAC. The code structure for these articles follows the pattern AB11XX, where XX denotes the actuator type and contact configuration. For example, AB1110-01 indicates a roller lever switch with 1NO+1NC contacts, while AB1110-02 represents a version with 2NC contacts. We also stock specialized versions with gold-plated contacts for low-current applications and high-temperature variants for extreme environments.
