Overview

The FD01FR10P-S is a real-coded decimal rotary DIP switch featuring 10 positions and a space-saving 7.2mm square footprint. This through-hole component utilizes gold-plated brass contacts for high reliability in low-logic applications, rated up to 0.4VA at 20V AC/DC. Its flush actuator is designed for screwdriver adjustment, making it ideal for semi-permanent configuration settings on a PCB.

Why Choose This Part

The switch offers high contact reliability through its gold-over-nickel plating, ensuring stable performance even in low-current logic circuits. Its compact 7.2mm DIP profile and standard 2.54mm pitch allow for easy integration into high-density PCB layouts and standard breadboards.

Applications

Address Setting
Configuring unique bus addresses for industrial sensors or RS-485 nodes.
Mode Selection
Switching between different firmware operation modes or diagnostic routines during field service.
Hardware Configuration
Setting baud rates or protocol parameters on embedded communication modules.
Prototyping
Manual input of BCD values during breadboard development and logic circuit testing.
