Indicator lights for distribution boards, also known as pilot lights, signal lamps, or panel indicators, are essential components in electrical panels and automation systems. These devices provide visual status indication for circuits, machinery, and processes, typically operating at voltages from 24V AC/DC up to 230V AC or 400V AC. They feature various lens colors (red, green, amber, blue, white) and mounting types such as 22mm or 30mm round cutouts, with options for LED or incandescent illumination. LED types offer long life, low power consumption, and high vibration resistance, while incandescent versions provide traditional warm light. Many models include integrated resistors for direct connection to control voltages, and some offer multi-voltage capability (e.g., 24-240V AC/DC). The degree of protection ranges from IP20 for panel interiors to IP65 for front-of-panel exposure, ensuring reliability in industrial environments.
These indicator lights are deployed across a wide range of sectors, including industrial automation, building management, power distribution, and process control. They are commonly installed in motor control centers (MCCs), distribution boards, control cabinets, and operator panels. Applications include signaling motor run/stop status, alarm conditions, power availability, and system faults. In commercial buildings, they indicate elevator operation, fire alarm status, or HVAC system states. In heavy industry, they are used in conveyor systems, pumping stations, and manufacturing lines. Their compact design allows integration into crowded panels, while high-visibility lenses ensure clear indication even in bright ambient light.
Key subcategories include standard 22mm round indicator lights (e.g., models like the Siemens SIRIUS 8WD or Eaton M22 series), 30mm heavy-duty types, and miniature indicators for PCB mounting. Common article codes follow patterns such as "M22-LED" for Eaton or "8WD4" for Siemens, often including voltage and color codes (e.g., "M22-LED230-R" for red at 230V). Other variants include flashing indicators, dual-color types (e.g., red/green), and those with built-in pushbuttons. The main articles are typically identified by a base code plus suffix for voltage and lens color, ensuring easy specification.
