Siemens 52PL4HX Pilot Button Red LED Indicator

Siemens 52PL4HX Pilot Button Red LED Indicator is a modular control device that pairs a push-button actuator with a built-in red LED indicator for immediate status signaling on panel-mounted control stations. It belongs to Siemens' Class 52 pilot devices, designed to integrate with compatible 52-series housings and accessories to create compact illuminated pushbuttons used in industrial automation. The 52PL4HX variant is specified with the 52AATH2B accessory, reflecting Siemens' approach to combine actuation with a clear visual indicator in a single unit; this configuration supports straightforward visual feedback in control circuits and can be wired into standard Siemens control panels where LED feedback is required. The red LED provides high-visibility indication even in challenging lighting conditions, helping operators quickly assess device status at a glance.
