Document Title: D2S Subminiature Basic Switch (Multiple Variations Detailed)

Overall Purpose: This document is a comprehensive datasheet/catalog entry for OMRON's D2S subminiature basic switches, detailing their specifications, variations, precautions for use, and application considerations. It appears targeted at engineers or purchasing agents who need to select and integrate these switches into their designs.

1. Switch Variations & Types:

The document describes several variations of the D2S subminiature switch, categorized primarily by lever style:

️· Standard (unspecified): Serves as the base model.
️· Hinge Roller Lever (D2S-10L2, D2S-5L2, D2S-5L2-F, D2S-01L2, D2S-01L2-F): Features a roller for enhanced leverage and potentially smoother operation.
️· Hinge Roller Lever (with Polyacetal Resin Roller): Specifying the material of the roller for optimized durability and performance.
️· Hinge-Steel Lever (D2S-10L2, D2S-5L2, D2S-5L2-F, D2S-01L2, D2S-01L2-F): Uses stainless-steel.

2. Key Specifications & Dimensions: (Specific dimensions are found throughout the document within the drawings and descriptions of each variation.)

️· Operating Force: Ranges are provided (see "Micro Loads" section below for more detail)
️· Overtravel: Specified for certain lever styles.
️· Free Position (FP): Dimension given for different lever styles.
️· Operating Position (OP): Dimension given for different lever styles.
️· Mounting: M2.3 screws with plane or spring washers. Tightening torque specified (0.23 - 0.26 N·m).

3. Operating Characteristics & "Micro Loads" Section (Critical for Design):

️· Normal Load vs. Micro Load: The document *strongly* emphasizes the distinction between using the switches for "normal" loads and "micro loads."
️· Micro Load Range: A chart (or more accurate description) depicts the acceptable current range for "micro load" applications. Going outside of this range can significantly reduce the switch's durability.
️· Contact Protection: If micro loads are used, a contact protection circuit is *highly recommended* to prevent excessive wear.
️· Reliability: A reference is made to a reliability level of 60% (λ 60).

4. Precautions & Correct Use:

️· Soldering: Detailed instructions provided for both automatic and manual soldering.
️· Mounting: Proper screw type and torque specified.
️· General: References a separate "Basic Switches Common Precautions" document for more general usage guidelines.

5. Important Application Notes and Warnings:

️· Reference Only: The examples given are for guidance only – actual function and safety need to be verified.
️· Critical Applications: A strong warning against using these switches in systems where failure could have serious consequences (e.g., nuclear control, railways, aviation, medical equipment). Requires double safety mechanisms.
