Limit Switches

The Limit Switches category stocks over 500 electromechanical position-sensing devices used by controls engineers, machine builders, and panel shops to detect the presence, position, or travel limits of moving machine components. Typical sub-types include standard industrial limit switches for general-purpose conveyor and actuator position sensing, watertight and oiltight limit switches rated for washdown or harsh-environment installations, and hazardous-location limit switches listed for use in Class I/II environments where ignitable gases or dusts may be present. Actuator styles across the category range from rotary lever arms and roller plungers to wobble sticks and adjustable rod levers, allowing precise mechanical trip-point configuration. Common selection criteria include operating voltage (AC or DC), contact configuration (NO, NC, or convertible), IP or NEMA enclosure rating, and ambient temperature range for low-temperature or high-heat applications.
