Auxiliary Control and Signalling Elements
When we talk about auxiliary control and signalling elements, we are referring to the backbone of human-machine interface (HMI) in any industrial installation. This category encompasses pilot devices such as pushbuttons, selector switches, emergency stop mushroom heads, pilot lights, and joysticks. These components are designed for panel mounting, typically in 22.5 mm or 30.5 mm cutouts, and operate at low control voltages (e.g., 24 VDC or 230 VAC). They feature robust contact blocks with silver alloy contacts, rated for mechanical endurance of over 1 million operations, and offer IP65 or IP67 protection ratings for harsh environments. The signalling technology predominantly uses high-brightness LEDs for status indication, ensuring long service life and low power consumption. These devices are modular, allowing for easy customization with interchangeable lenses, legends, and contact configurations (e.g., 1NO+1NC, 2NO+2NC).
These elements are fundamental in control panels, distribution boards, and automation cabinets across various sectors. You will find them in industrial manufacturing lines for machine start/stop and emergency stop functions, in process automation for status indication of pumps and valves, in building management systems for HVAC and lighting control, and in power generation plants for generator and breaker control. They are also critical in material handling equipment, such as cranes and conveyors, and in marine and offshore applications where reliability and ingress protection are paramount.
Within this category, the most relevant subcategories include pushbuttons (flush, extended, and illuminated), selector switches (2-position and 3-position), emergency stop devices (twist-to-release and key-release), and pilot lights (steady and flashing LED). The Eaton RMQ-Titan series is a prime example, with article codes structured as RMQ-Titan-M22-XXXX, where XXXX denotes the specific function (e.g., M22-DL for pilot lights, M22-DR for pushbuttons, M22-W for selector switches). Other key series include the Siemens SIRIUS ACT and the Schneider Electric Harmony XB4/XB5 ranges, which follow similar coding conventions for modular components.
