Technical Specifications and Coding System for Switch Components

This document outlines a detailed coding and specification system for various switch components, including buttons, terminals, housings, and actuators. It provides parameters for dimensions, electrical ratings, mechanical actions, and special features such as waterproofing and illumination.

1. Button Length and Codes

• Button lengths are standardized with codes indicating sizes: 5mm, 10mm, 15mm, and 17mm.
• Examples of button length codes include KA5 2K-, KA5 KT-, with suffixes indicating length (5/, 10/, 15/).

2. Special Requirements and Features

• Waterproof and common (non-waterproof) options are specified with distinct codes.
• Illuminator presence is indicated, differentiating between illuminated and non-illuminated terminals.
• Special requirements can include waterproofing, circuit variations, and button options.

3. Electrical Ratings and Durability

• Switches are rated for currents such as 10A at 250VAC, with durability ratings of 100,000 or 30,000 cycles depending on the model.
• Additional ratings include 11A and 21A options, with corresponding codes.

4. Mechanical and Operational Parameters

• Operating forces are categorized, for example: A = 100±30gf, B = 250±50gf, C = 500±100gf.
• Button sizes are coded as A (10mm), B (12mm), C (14mm), D (16mm).
• Action types and pole configurations are indicated by codes such as 1, 2, 3, and 11M.

5. Termination and Housing

• Terminal types are coded, with options for no terminal, common terminal, and waterproof terminal.
• Housing options include plating (e.g., chromium plating) and ordinary finishes, coded as A or B.

6. Circuit and Button Options

• Circuits include normally open (NO) and normally closed (NC) configurations.
• Button options include momentary and alternate actions.
• Markings for front and back sides are specified for identification.
