22A20 Switch Series:Illuminated Selector Switches

Product catalog summary

1. Switch Types and Configurations

The document details illuminated selector switches available in 90°-2 position and 45°-3 position variants. Both maintained (toggle) and spring return types are offered, with contact configurations including 1NO, 1NC, 2NO, 2NC, and mixed 1NO-1NC. Metal bezel versions provide enhanced durability and aesthetic appeal, maintaining the same positional and contact options as standard models.

2. Contact and Illumination Options

Contacts are classified as Normally Open (NO) or Normally Closed (NC), with multiple configurations to suit various control needs. Illumination is provided via built-in LED or incandescent lamps, supporting operating voltages from 6V up to 240V AC/DC. LED voltage codes include 2 (6V), 3 (12V), 4 (24V), H (110V), and M3 (230/240V), while incandescent lamps cover 6V, 12V, and 24V options, with some models supporting higher voltages.

3. Lens Colors and Identification Codes

Lens colors available are Amber (A), Green (G), Red (R), Blue (S), White (W), and Yellow (Y). These colors are encoded within model numbers to specify the illumination color for easy identification.

4. Electrical Ratings and Mounting Specifications

All switches are rated for a maximum voltage of 250V AC/DC. Panel mounting supports thicknesses ranging from 0.8 mm to 6 mm, ensuring compatibility with a variety of panel designs.

5. Mechanical Dimensions

Standard switches require a panel cutout diameter of approximately 28.8 mm, while metal bezel versions need a larger cutout around 34.8 mm. Overall dimensions vary slightly by model and bezel type, with detailed length, width, and height measurements provided to ensure proper fit and installation.

6. Model Numbering System

Model numbers encode critical information including switch type, contact configuration, lamp type, operating voltage, and lens color. The suffix "-U" denotes metal silhouette bezels, aiding in quick identification of mechanical features.

7. Recommendations and Best Practices

Select switch type based on required positions, contact arrangements, and return mechanisms (maintained or spring return).
Choose lamp type and voltage to match the power supply and illumination needs of the application.
Verify panel thickness compatibility to ensure secure and proper mounting.
Use metal bezel versions for applications demanding enhanced mechanical robustness and improved aesthetics.

8. A204F Series Specifics

The A204F series features 45°-3 position knobs with spring return mechanisms and metal bezels. Contact configurations include 1NO, 1NC, 2NO, 2NC, and mixed types. Illumination options mirror the general series with LED and incandescent lamps across multiple voltages and colors. Panel cutout sizes range from approximately 45.8 mm to 54.8 mm, with bezel diameters between 28.8 mm and 34.8 mm. Model numbers encode detailed specifications, facilitating precise selection.

Summary

This document comprehensively covers illuminated selector switches, including standard and metal bezel models, multiple contact and illumination configurations, electrical ratings, and mechanical dimensions. It provides essential guidance for selecting switches tailored to operational requirements, ensuring compatibility with panel designs and application needs. The A204F series exemplifies these features with robust design and versatile options suitable for industrial control panels.
