G5 Series Basic Micro Switch G5 in Ice Maker

Key Features and Specifications

Temperature Resistance

The G5 series offers multiple temperature grades, including 25T85 (-25°C to +85°C), 25T125 (-25°C to +125°C), and 25T150 (-25°C to +150°C) . This wide range makes it suitable for ice makers, where components must withstand extreme cold during freezing cycles and potential heat from motor operations.

Electrical Performance

Rated Current: Up to 16A (resistive load) at 125/250VAC .

Electrical Life: Over 50,000–100,000 cycles (dependent on load) .

Mechanical Life: Exceeds 1,000,000–10,000,000 cycles, ensuring longevity in high-frequency use .

Snap Action Mechanism: Provides rapid contact opening/closing (≤1mm travel) for reliable triggering in ice thickness detection or motor control .

Environmental Protection

IP64/IP67 Waterproof Options: Select models feature dustproof and splash-resistant designs (IP64) or submersion resistance (IP67), ideal for ice makers’ humid environments .

Global Certifications: Compliant with ENEC, CQC, ROHS, and REACH standards, ensuring safety and regulatory compliance .

Design Flexibility

Terminals: Available with quick-connect or solder terminals for easy integration .

Lever Configurations: Optional roller or straight levers adapt to various actuation mechanisms, such as ice level sensors or door switches .

Compact Size: Measures approximately 27.8×10.3×15.9mm, fitting into space-constrained ice maker assemblies .

Application in Ice Makers

Ice Level Detection: The G5 switch monitors ice bin fullness via a float ball or mechanical arm. When ice reaches a preset level, the switch triggers the compressor to pause, preventing overflow .

Door Interlock: Ensures safe operation by cutting power to the ice maker when the door is opened, using a snap-action mechanism to detect door position .

Defrost Cycle Control: Activates defrost heaters or water pumps by sensing temperature changes or mechanical movements during defrosting, optimizing energy efficiency .

Motor Protection: Safeguards compressors and fans by interrupting power in case of jams or overloads, leveraging high inrush current tolerance (e.g., 40A for G5Q-EL2 variants) .

Technical Advantages

High Sensitivity: Operates with minimal force (7–600gf), ensuring reliable actuation even with delicate mechanisms like ice thickness probes .

Vibration & Shock Resistance: Withstands 10–55Hz vibrations and 100g for>1N loads, maintaining stability in noisy, dynamic environments .

Cost-Effective Design: Offers comparable performance to premium brands like Honeywell and Omron at a competitive price point .

For Freezing Zones: Choose 25T85 or 25T125 grades for consistent performance in sub-zero temperatures.

For Wet Environments: Opt for IP67-rated models (e.g., G5H10-E1P050B03U) to prevent water ingress .

For High-Power Circuits: Select variants with silver alloy contacts (AgNi) for 16A loads, ensuring low contact resistance and long life .

The G5 Series Basic Micro Switch delivers precision, durability, and versatility in ice maker applications, making it a trusted choice for OEMs and repair markets worldwide. Its robust design and global certifications ensure seamless integration into modern ice-making systems, enhancing efficiency and user safety
