LW5D Rotary Switch

Product Overview

The LW5D Rotary Switch is a versatile electrical component primarily used for circuit changeover, electrical measuring instrument control, and motor control. Unlike standard rotary switches, it is built to handle heavy loads, with a maximum rating of 30A and compatibility with working voltages ranging from 125V to 500V (AC/DC), ensuring it performs consistently in high-power industrial setups.

Crafted with a durable metal or plastic enclosure, the switch offers optional waterproof protection, expanding its usability in damp, dusty, or outdoor environments. Its mechanical design prioritizes long-term reliability: the switch boasts a no-load mechanical life of 0.3×10⁶ operations (at 300 cycles per hour) and maintains stable performance under loaded conditions—including 0.01×10⁴ operations for AC-15/DC-13 loads and 0.1×10⁴ operations for AC-3/AC-4 loads (at 120 cycles per hour).

Backed by CE and ISO9001 certifications, the LW5D Rotary Switch adheres to strict quality and safety standards, ensuring compliance with global industrial regulations. Whether integrated into small-scale control panels or large OEM equipment, it delivers consistent, trustworthy performance that minimizes downtime and reduces maintenance costs.

Key Features

The LW5D Rotary Switch’s design focuses on durability, customization, and adaptability—addressing the diverse needs of industrial applications. Below are its standout features:

Heavy-Duty Performance & Durable Build

High Current/Voltage Rating: Supports a maximum current of 30A and working voltages up to 250V (optimal for heavy-load scenarios), with rated thermal current (Ith) of 16A to prevent overheating during prolonged use.

Robust Enclosure: Constructed from high-grade metal or impact-resistant plastic, the switch resists corrosion, mechanical impact, and wear. Optional waterproof variants further extend its use in wet or dusty environments (e.g., outdoor electrical cabinets, marine equipment).

Long Mechanical Life: Engineered for longevity, with no-load mechanical life of 0.3×10⁶ operations and load-specific life cycles tailored to industrial demands—ensuring it outlasts standard switches in high-frequency use cases.

Customizable Configurations

Flexible Poles & Positions: Offers customizable pole counts (1 to 6 poles) and position options (2 to 12 positions), allowing engineers to tailor the switch to specific circuit changeover or control needs (e.g., 8-position setups for multi-mode equipment).

Load Compatibility: Designed to handle diverse load types, including AC-15 (inductive loads), AC-3/AC-4 (motor loads), and DC-13 (electromagnetic loads), with rated working currents (Le) optimized for each: 4.6A (AC-15, 220V), 2.6A (AC-15, 250V), 12A (DC-3, 380V), and 3.5A (AC-4, 380V).

Applications

The LW5D Rotary Switch’s versatility and durability make it suitable for a wide range of industrial and commercial use cases. Below are its primary applications:

Industrial Machinery Control

Motor Control: Used to start, stop, or switch between motor operating modes in heavy machinery (e.g., conveyors, pumps, manufacturing robots). Its 30A rating handles the high current demands of industrial motors, while customizable positions enable precise mode selection.

Circuit Changeover: Facilitates safe, reliable switching between power sources or circuit paths in industrial control panels (e.g., backup power systems, multi-line production equipment), reducing the risk of electrical faults.

Electrical Measuring Instruments

Integrated into test equipment, voltage meters, and current monitors to select measurement ranges or calibrate readings. The switch’s stable contact resistance ensures accurate signal transmission, critical for precision instrumentation in labs or quality control facilities.

Harsh Environment Systems

Outdoor/Marine Equipment: Waterproof variants are ideal for outdoor electrical systems (e.g., solar power inverters, agricultural machinery) or marine applications, where resistance to moisture and corrosion is essential.

Dusty/High-Temperature Settings: Used in factories, mining operations, or automotive assembly lines—its durable enclosure protects internal components from dust, vibration, and moderate temperature fluctuations.

OEM Equipment Integration

Embedded into OEM products such as switching power supplies, inverters, and solar controllers (common in LEYU’s product ecosystem). Its customizable design allows seamless integration into diverse equipment, while bulk pricing supports large-scale production.
