Rocker Switches

1. Overview

Rocker switches are electric switches featuring a rocking mechanism that toggles between on/off states. They are widely used in industrial, automotive, and consumer electronics for their durability and clear tactile feedback. Modern advancements have enhanced their load capacity, environmental resistance, and integration capabilities with smart systems.

2. Main Types and Functional Classification

Type	Functional Characteristics	Application Examples
Single-Pole Single-Throw (SPST)	Simple on/off control with one circuit path	Lighting systems, small appliances
Single-Pole Double-Throw (SPDT)	Switches between two circuits with one input	Motor direction control, HVAC systems
Double-Pole Single-Throw (DPST)	Simultaneously controls two circuits	Industrial machinery power isolation
Double-Pole Double-Throw (DPDT)	Switches two inputs between two outputs	3D printer heater control, robotics
Illuminated Rocker	Integrated LED indicators for status visibility	Aircraft panels, medical equipment

3. Structure and Components

Typical construction includes: - Actuator: Rocker arm with ergonomic design (PC/ABS material) - Contact System: Silver alloy contacts with anti-oxidation coating - Housing: Flame-retardant thermoplastic (UL94 V-0 rated) - Mounting Hardware: Threaded bushing with 12mm/16mm standard sizes - Terminal Types: Quick-connect terminals (Faston) or PCB pins

4. Key Technical Specifications

Parameter	Value Range	Importance
Rated Current	0.1-20A	Determines load handling capacity
Rated Voltage	12-600VAC/DC	Defines operational voltage limits
Electrical Life	50,000-200,000 cycles	Indicates longevity under rated load
Contact Resistance	5-50m	Affects power efficiency and heat generation
Insulation Resistance	100M min	Ensures safety isolation
Operating Temperature	-40 C to +125 C	Defines environmental suitability

5. Application Fields

Industrial: CNC machine controls, PLC panels
Automotive: Vehicle lighting systems, battery management
Medical: Diagnostic equipment, patient monitoring devices
Aerospace: Avionics control panels, actuator systems
Consumer Electronics: Smart home hubs, gaming consoles

6. Leading Manufacturers and Products

Manufacturer	Key Products	Special Features
Eaton	Series 15X	UL489 certified, 63A rating
TE Connectivity	ET Series	IP67 sealed models, -55 C operation
C&K Components	KSC Series	100,000 cycle lifespan, RoHS compliance
Omron	A22 Rocker	Integrated LED options, 48VDC control

7. Selection Guidelines

Key considerations: - Current/voltage requirements with 20% safety margin - Environmental factors (temperature, humidity, vibration) - Certification needs (UL, CE, RoHS) - Actuator style (standard, guarded, illuminated) - Terminal compatibility with existing systems - Expected mechanical/electrical lifespan

8. Industry Trends

Emerging trends include: - Integration with IoT-enabled control systems - Development of sub-miniature waterproof models (IP68) - Graphene-coated contacts for reduced resistance - Smart switch modules with embedded sensors - Increased adoption in renewable energy systems
