3 Position Rocker Switch

A 3 Position Rocker Switch is a versatile electrical component featuring three distinct states: ON-OFF-ON or ON-ON-ON, activated by rocking the lever. Commonly used in industrial, automotive, and household applications, it allows control over multiple circuits or functions. The switch's durable design ensures reliable performance, with options for illuminated or non-illuminated variants. Its compact form factor and ergonomic operation make it ideal for panels and control systems. Constructed from materials like polycarbonate or metal, it offers resistance to wear, moisture, and high temperatures. Wiring configurations vary, supporting SPDT or DPDT setups for flexible integration.

Wiring and Mounting Guide

This 3-position rocker switch supports both SPDT and DPDT wiring configurations, allowing for flexible circuit control. Typical applications include ON-OFF-ON (center-off) or ON-ON-ON switching for multi-mode control. It fits standard 22.5mm panel cutouts and is equipped with 6.35mm quick-connect terminals, compatible with 12–24AWG wires.

A wiring diagram is recommended for proper installation. Ensure correct orientation of terminals and secure connection using insulated female connectors to prevent short circuits.

Siemens Automation Equipment Rocker Switch's Product Operating Principle

This switch integrates three independent buttons, each comprising a switching mechanism with an internal spring and metal contacts. When any button is pressed, the contacts close, allowing control of currents up to 20A; upon release, the contacts reset, disconnecting the circuit. This design ensures stable and reliable operation under heavy load conditions.

Server Power Modules Rocker Switch's Product Functions

Circuit Control: Enables precise on/off switching of device circuits.
Multi-Function Switching: Different buttons correspond to various operating modes, meeting complex control requirements.
Safety Protection: Ensures stable power cutoff under high load conditions, preventing overload and circuit failures.

The 3-Position Rocker Switch is a versatile electromechanical component designed for robust control applications. Here are its key features with technical specifications:

1. Tri-Stable Circuit Control: Features ON-OFF-ON (SPDT) or ON-ON-ON (3PDT) configurations with contact ratings up to 16A/250VAC (IEC 60947 compliance), enabling multi-circuit management in industrial panels.

2. IP67 Sealed Construction: Engineered with silicone-sealed actuators and nylon 6/6 housings, achieving complete dustproof performance and 30-minute waterproofing at 1m depth per IEC 60529 standards.

3. High-Temperature Tolerance: Operates reliably in -40°C to +85°C environments (UL94 V-0 flame-retardant materials), with >100,000 mechanical cycles at 25°C/60% RH per MIL-S-22885/4 testing.

4. Tactile Position Indication: Incorporates ±0.5mm precision-molded detents with 50±10gf actuation force (measured per EN 61058-1), delivering positive feedback for blind operations.

5. EMI/RFI Shielding: Nickel-plated brass contacts reduce contact resistance to <2mω initially="">

6. Mounting Flexibility: Compatible with 22.5mm cutouts (DIN 43650 standard) and features 6.35mm quick-connect terminals accepting 12-24AWG wires for rapid installation.

These engineered characteristics make the 3-position rocker switch ideal for automotive, marine, and industrial equipment requiring fail-safe circuit switching under demanding conditions.

Power Control Modules Rocker Switch's Product Applications

• Industrial Automation Control:

  Example: Used in conveyor belt start/stop systems on automated production lines

  Multiple buttons control different circuits, enabling precise sectional management. This ensures that the production line can be promptly halted in emergencies, safeguarding safety.

  
  

• Power Management Systems:

  Example: Applied in main power switching panels of server power modules.

  The high load capacity ensures stable switching of the main power supply during continuous operation, protecting critical equipment from current fluctuations.

  
  

• High-Power Household Appliances:

  Example: Integrated into the power control modules of large air conditioners or washing machines.

  Precisely controls circuit connectivity, ensuring the safe start-up and shutdown of high-power devices. This extends the equipment's lifespan and enhances user safety.
