Molded Lead Wires On Left Side Micro Switch G303

  • Left-Side Molded Lead Wires: Unique design with lead wires molded on the left (plunger side) for easy wiring in tight spaces and complex assemblies.

  • SPST-NC Circuit: Single Pole Single Throw (Normally Closed) configuration for reliable switching in specialized circuits.

  • IP67 Protection: Dust-tight and water-resistant, ideal for harsh environments.

  • Compact & Robust: Small size with high durability, meeting global safety approvals for worldwide use.

  • Long Service Life: Up to 500,000 mechanical cycles and 100,000 electrical cycles (part number dependent).

  • Versatile Applications: Suitable for automotive electronics, appliances, and industrial control systems with flexible lever and terminal options.

The Unionwell G303-130G38B14-FA300U Micro Switch combines precision engineering with a unique left-side molded lead wire design, offering seamless integration into space-constrained and complex electronic systems. With an SPST-NC (Single Pole Single Throw, Normally Closed) circuit and a maximum operating force of 130gf, this switch delivers reliable performance in demanding applications.


Unique Design for Easy Installation

Featuring molded lead wires on the left side (plunger side), this micro switch simplifies wiring in tight spaces, making it an excellent choice for intricate assemblies where traditional terminal configurations may pose challenges. The compact form factor doesn’t compromise on durability—an IP67 rating ensures protection against dust and water ingress, even in harsh environments.


Performance & Compliance

Built to international safety standards, the G303 excels in diverse electrical and mechanical conditions:


  • Electrical Ratings: Supports 0.1A at 125/250VAC, 3A at 12VDC, 0.1A at 48VDC, and μ1E5 for versatile voltage/current needs.

  • Longevity: Engineered for 500,000 mechanical cycles and 100,000 electrical cycles (dependent on part number), reducing maintenance and replacement costs.

  • Environmental Resilience: Operates reliably from -40°C to +85°C and withstands up to 85% relative humidity, ensuring performance in extreme conditions.


Applications

Perfect for:


  • Automotive Systems: Seat controls, door sensors, and safety mechanisms requiring compact, weather-resistant switches.

  • Household Appliances: Small appliances, power tools, and smart devices where space efficiency is critical.

  • Industrial Equipment: Robotic arms, machinery sensors, and control panels that demand durable, compliant components.
