Schurter DMTH 2.54mm THT DIP Switches

Introduction

The Schurter DMTH series is a range of compact, through-hole DIP switches designed for dependable manual configuration in electronic equipment. With a standard 2.54 mm pitch, low-profile body, and multiple switch-position options, these components provide a practical way to set operating modes, addresses, and device parameters directly on a PCB.

Part Description

Schurter DMTH DIP switches are through-hole mounted configuration switches intended for reliable board-level use. Their 2.54 mm pitch supports common PCB layouts and conventional assembly processes, while the low-profile construction helps conserve vertical space within enclosures.

The series is available with up to 12 switch positions, allowing designers to create a variety of binary configuration combinations in a single component. Typical uses include selecting hardware options, assigning device addresses, enabling or disabling functions, and setting operating modes without requiring firmware changes or external programming equipment.

Key characteristics include:

• Standard 2.54 mm terminal pitch
• Through-hole terminals for secure PCB mounting
• Low-profile mechanical design
• Up to 12 individual switch positions
• Mechanical life rated for approximately 2,000 cycles
• Operating temperature range of -40°C to +85°C
• Manual configuration capability for production, service, and field setup

Applications

Potential applications for Schurter DMTH DIP switches include:

• Device address selection
• Communication node identification
• Hardware mode selection
• Configuration of control boards
• Programming of binary options
• Feature enable or disable settings
• Factory-default configuration selection
• Test and calibration settings
• Security or access configuration
• Power-management mode selection
• Sensor module setup
• Timing and logic option selection

Industries

Schurter DMTH DIP switches can be used across many industries, including:

• Industrial automation
• Building automation
• Consumer electronics
• Telecommunications
• Networking equipment
• Test and measurement
• Medical electronics
• Transportation systems
• Energy management

Usage Ideas

1. Configurable RS-485 Sensor Node

Use an 8-position DMTH switch to assign a unique RS-485 address to each sensor node on an industrial communication network. The switch settings can be read by a microcontroller during startup.

2. Multi-Mode Power Supply Controller

Install a DIP switch on a power-control PCB to select between operating profiles such as normal operation, low-power mode, diagnostic mode, and factory test mode.

3. Educational Binary Input Board

Create a training board where each DIP switch position represents a binary bit. Students can use the switches to enter numbers, logic states, or configuration values into a microcontroller project.

Conclusion

The Schurter DMTH series offers a simple, durable, and space-conscious method of adding manual configuration capability to printed circuit boards. Its standard 2.54 mm pitch, through-hole mounting, support for up to 12 positions, and broad operating-temperature range make it suitable for a wide variety of industrial, commercial, and embedded electronic designs.
