Straight PCB Terminals Micro Switch G303

  • Straight PCB Terminals (0.6mm Width): Designed for easy, secure soldering onto printed circuit boards, ideal for space-efficient and compact designs.

  • SPST-NO Circuit: Single Pole Single Throw (Normally Open) configuration for reliable, direct-actuation switching in simple circuits.

  • IP67 Rated: Dust-tight and water-resistant, ensuring performance in harsh environments with exposure to moisture or debris.

  • Compact & Robust: Small form factor with high durability, meeting global safety approvals for worldwide industrial and consumer applications.

  • Long Service Life: Up to 500,000 mechanical cycles and 100,000 electrical cycles (part number dependent) for low-maintenance, long-term use.

  • Versatile Design: Offers multiple lever options and wiring terminals, suitable for automotive electronics, appliances, and industrial control systems.

The Unionwell G303-130P00C49J-T370 Micro Switch combines precision engineering with a straight PCB terminal design, delivering seamless integration into compact electronic systems. With an SPST-NO (Single Pole Single Throw, Normally Open) circuit and a maximum operating force of 130gf, this switch is optimized for reliable, direct contact in space-constrained applications.


Streamlined PCB Integration

Featuring 0.6mm width straight PCB terminals, the G303 ensures easy soldering and secure mounting on printed circuit boards, reducing assembly time and enhancing design efficiency. Its compact size makes it ideal for applications where space is limited, while the IP67 rating provides robust protection against dust and water ingress—perfect for demanding environments.


Performance & Compliance

Built to international safety standards, this micro switch excels in diverse electrical and mechanical conditions:
  • Electrical Ratings: Supports 0.1A at 125/250VAC, 3A at 12VDC, 0.1A at 48VDC, and μ1E5, accommodating a wide range of voltage and current requirements.

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

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


Ideal Applications

Perfect for:
  • Automotive Electronics: Seat adjustment systems, door sensors, and compact safety switches in vehicles.

  • Household Appliances: Small kitchen gadgets, power tools, and smart home devices requiring space-efficient switching solutions.

  • Industrial Controls: Robotics, machinery limit switches, and automation equipment that demand durable, compliant components.
