Switch Selection Guide Summary

1. Overview
This document provides a detailed guide for selecting switches based on their electrical ratings and physical sizes. It categorizes switches by their power ratings, voltage capacities, and form factors to assist in choosing the appropriate switch for specific applications.

2. Electrical Specifications
The guide lists switches with varying current and voltage ratings, primarily focusing on AC and AC/DC applications. Key ratings include:

Low power switches rated at 0.4VA at 28V AC/DC, available in ultra-miniature (G, GW), subminiature (A, B), and miniature (M, M2T) sizes.
Medium power switches rated from 3A to 6A at voltages ranging from 125V to 250V AC, including miniature types such as CWT, CWS, M, and M2T.
Higher power switches rated from 10A to 30A at 125V AC or AC/DC, including standard sizes P, WT, S (with low, medium, and high capacitance variants), WR, JWL, JWS, JWM, and SW series.
Some switches support dual voltage ratings (125/250V AC) and higher current capacities up to 50A.

3. Physical Form Factors
The switches are categorized by size and type:

Ultra-miniature (G, GW)
Subminiature (A, B)
Miniature (M, M2T, CWT, CWS)
Standard (P, WT, S, WR, JWL, JWS, JWM, SW)

Each form factor corresponds to specific current and voltage ratings, enabling selection based on space constraints and electrical requirements.

4. Additional Features
Some switches include wire lead options for easier wiring and installation. Capacitance levels (low, medium, high) are specified for certain standard S series switches, indicating suitability for different electrical noise and filtering requirements.

5. Summary of Key Parameters

Switch Type	Power Rating	Voltage	Current	Form Factor	Notes
Ultra-miniature	0.4VA	28V AC/DC	—	G, GW	Low power, compact size
Subminiature	0.4VA	28V AC/DC	—	A, B	Low power
Miniature	0.4VA to 6A	28V AC/DC to 250V AC	3A to 6A	M, M2T, CWT, CWS	Medium power options
Standard	10A to 50A	125V AC to 250V AC/DC	10A to 50A	P, WT, S, WR, JWL, JWS, JWM, SW	High power, multiple capacitance levels

6. Recommendations
When selecting a switch, consider the required current and voltage ratings, physical size constraints, and any special features such as capacitance level or wiring type. For low power signal switching, ultra-miniature or subminiature types are suitable. For higher power applications, standard size switches with appropriate current ratings should be selected.
