Introduction

    Rotary DIP switches play a crucial role in electronic devices. This article delves into their design principles, mechanical structures, and application engineering details, revealing how they meet user needs and provide reliability.

1. Details of the Rotary Mechanism

Design Principles

The core of the rotary mechanism is the rotation axis, typically made of highly wear-resistant material to ensure prolonged use without easy wear. Grooves or scales on the axis help users precisely select different positions.

Lubrication System

To ensure smooth rotation, the design may include a carefully crafted lubrication system to reduce friction, improving rotational precision and durability.

2. Technical Considerations in Contact Design

Choice of Conductive Material

Contacts are often made of silver alloy due to its excellent conductivity and corrosion resistance, ensuring reliable electrical connections.

Contact Layout

Precise contact layout is crucial to minimize contact resistance during position switching. Engineers may optimize the layout to minimize contact resistance effectively.

3. Design Details of Multi-Position Switches

Mechanical Locking System

To ensure stability between different positions, a mechanical locking system may be employed to prevent accidental switching due to vibration or impact.

Positioning Springs

Introducing positioning springs ensures that the switch receives sufficient force feedback at each position, enhancing the precision of user operations.

4. Engineering Techniques of Encoding Switches

Manufacturing of Encoder Disk

The manufacturing of the encoder disk requires high engineering precision to ensure each position's code is unique. Advanced machining techniques, such as laser engraving, may be used.

Position Resolution Algorithms

Internal systems may include advanced position resolution algorithms that interpret the exact switch position in real-time by reading the code, providing a higher level of control.

5. Anti-Touch and Anti-Bounce Design

Debouncing Circuit

To prevent triggering due to mechanical fluctuations, the design may include a debouncing circuit to ensure that only genuine operations lead to signal changes.

Mechanical Anti-Touch

Some designs may introduce mechanical devices like anti-touch buttons to prevent inadvertent changes in switch positions.
