DRD10E04 BCD Rotary DIP Switch

Overview

The DRD10E04 is a 10-position BCD (Binary Coded Decimal) coded rotary DIP switch from TE Connectivity Alcoswitch series. Designed for through-hole mounting, this switch features a flush actuator that allows for compact, low-profile PCB designs while providing reliable logic-level encoding.

Why Choose This Part

This switch offers a 10x10mm footprint with BCD output, simplifying the interface to microcontrollers by reducing the number of GPIOs required to read 10 positions. It is rated for operation between -30C and +85C, making it suitable for standard industrial environments.

Applications

Getting Started

To integrate the DRD10E04, connect the common pin to your logic voltage or ground and use pull-up/pull-down resistors on the four output pins (1, 2, 4, 8) to read the BCD state into your MCU. Ensure the 20V maximum rating is respected during circuit design, and verify the flush actuator access requirements for your enclosure.
