PWEngraving Engraved Legend Plates For 30mm Switches
Engraved legend plates from PWEngraving deliver customized labeling for equipment panels. The product line includes options for different sizes and colors, making it adaptable to various control setups. The plates are designed for durability in industrial settings, with clear engravings that resist wear and fading over time. The 30 mm option aligns well with standard pushbutton and selector switch mounts used in HVAC and manufacturing panels. Engraving customization helps ensure each function is unmistakable at a glance.
Siemens 52NL26 Heavy Duty Inscribed Legend Plate
This Siemens legend plate is configured for identification of selector switch units. It is designed to fit 30 mm threaded mounting shafts and is compatible with standard 3/4″ NPSM shafts, though mounting hardware is not included. The plate features an “OFF-ON” inscription that provides a quick visual cue for operator states. Built for industrial environments, it emphasizes legibility and reliability, supporting consistent operation across multiple machines or panels.
Eaton 10250TS51 Square Legend Plate
The Eaton 10250TS51 square legend plate is designed for use with the 10250T series selector switches and roto-push operators. It supports 30 mm threaded mounting shafts (not included) and ships with preprinted legends for straightforward identification. The product aims to improve visibility and reduce operator errors by providing crisp, durable lettering suitable for frequent use. This makes it a solid choice for panels that require standardized labeling across equipment.
Eaton 10250TM42 Round Legend Plate
This Eaton round legend plate is built for 30 mm threaded mounting shafts and pairs with the 10250T selector switch family. It carries a clear “OFF ON” inscription, enabling operators to confirm a switch’s state at a glance. The plate’s design emphasizes durability and readability in industrial environments, where equipment operates under demanding conditions. The round shape offers flexibility for compact control panels without sacrificing clarity.
Legend Plate “START” With Holder (22mm)
This Alpinetech legend plate, designed for 22 mm switches, provides a budget-friendly option with easy installation. While it targets 22 mm mounting shafts, it serves as a practical reference in mixed-panel environments where 30 mm components are complemented by smaller controls. The package typically includes a holder and legible black lettering on a silver background, offering good contrast for quick identification. It remains a useful alternative when 30 mm availability is limited.
Legend Plate Man AUTO With Holder (22mm)
The Legend Plate Man AUTO with Holder is another 22 mm option from Alpinetech, offering simple installation and legible labeling. It is suited for control panels that mix smaller and larger components, allowing operators to maintain consistent labeling practice. Like the START plate, it provides a practical, cost-conscious choice for non-30 mm applications or for replacement parts in multi-size panel setups.
Legend Plate “ON Off ON” With Holder (22mm)
This Alpinetech legend plate features the “ON Off ON” inscription for quick state recognition in 22 mm assemblies. It includes a holder for secure mounting and is designed to be visually distinct against light or dark panel backgrounds. While not a direct 30 mm solution, it remains a viable addition for mixed-control panels where multiple switch sizes are deployed and standardized labeling is required.
Buying Guide: Key Considerations For Legend Plates
- Mounting compatibility: Confirm shaft size (30 mm vs 22 mm) and whether the plate requires an accompanying holder or adapter. If your switches are standard 30 mm, prioritize plates explicitly labeled for 30 mm shafts.
- Readability: Look for high-contrast lettering (e.g., black text on silver or white text on dark backgrounds) and adequate plate size. Engravings or preprinted legends should remain legible under typical lighting and wear.
- Durability and material: Choose plates made from sturdy plastics or metal that resist impact, chemicals, and abrasion in industrial settings. Some plates are designed for food-grade or washdown environments; verify suitability for your application.
- Customization options: For controlled environments, engraved or labeled plates can reduce misoperation. Check for customization options in terms of text, color, and size to fit your panel design.
- Installation effort: Some plates come with easy-to-install features and holders, while others require additional hardware. Consider whether quick swapping or permanent mounting better suits your workflow.
- Compatibility with existing components: Ensure that the plate’s dimensions align with your switch or actuator’s mounting pattern to avoid fit issues on existing panels.
- Inventory and replacement: If you manage multiple panels, choose standardized plates across your fleet to simplify maintenance and future replacements.
