Switch Selection Guide Overview

This document provides a detailed guide on various switch types, their electrical ratings, and form factors to assist in selecting the appropriate switch for specific applications.

1. Electrical Ratings and Switch Types

• Subminiature Switches: Typically rated at 0.4VA at 28V AC/DC (e.g., HB2 series) and 0.1A at 30V AC/DC (HB series).
• Miniature Switches: Ratings vary from 0.4VA at 28V AC/DC (KB, UB, UB2, YB series) to higher current ratings such as 1A at 125/250V AC (KB series), 3A at 125/250V AC (YB, LP01, LB series), and up to 5A at 125/250V AC (UB, UB2 series).
• Photo Interrupters: Standard and subminiature types available, typically rated at 5V (FP01 and DSB series), with plug options for connection.
• Ultra-miniature Switches: Include various models (G3B, G3T, SS3, HP03) rated at 0.4VA at 28V AC/DC, with some models supporting up to 3VA at 28V DC (HP03).
• Ultra-miniature Slide Switches: Current ratings range from 25mA to 100mA at voltages between 5V and 50V DC (JS, CB3, ND3, FR02 series).

2. Form Factors and Mounting Styles

• Button and Slide Switches: Various miniature and subminiature options available.
• Gull Wing Packages: Ultra-miniature switches with gull wing leads for surface mounting, including G3B, G3T, SS3, and HP03 series.

3. Key Parameters and Recommendations

• Ensure voltage and current ratings match application requirements to avoid switch failure.
• Consider form factor and mounting style for PCB layout compatibility.
• Photo interrupters offer low voltage operation with plug-in connection options for ease of integration.
• Ultra-miniature switches provide compact solutions for space-constrained designs with varying current capacities.

Note: For detailed plug options and connection methods, refer to the FP01 series documentation.
