Multicomp Pro Snap Action Micro Switch Hinge Lever SPST-NC 3A

The Multicomp Pro Snap Action Micro Switch (MP005550) is a dependable SPST-NC (Single Pole Single Throw, Normally Closed) miniature switch, engineered for precise control in low-power circuits. It features a hinge lever actuator for reliable operation, making it suitable for applications requiring a tactile feedback mechanism. The switch offers a low contact resistance of 100mΩ and a high insulation resistance of 100MΩ, ensuring efficient electrical performance and safety.

Constructed as a compact, miniature device, it utilises PC pin terminals for straightforward PCB mounting. With a maximum contact current rating of 3A at 125V AC, it is designed for switching applications in various electronic and control systems. The switch is activated with a light operating force, requiring a maximum of just 26 grams-force.

Key Features

• Reliable Switching: SPST-NC contact configuration provides a stable normally closed circuit that opens upon actuator pressure.
• Hinge Lever Actuator: The lever design offers a positive snap action and is ideal for applications where the actuating force is applied from a specific angle.
• Efficient Performance: Low contact resistance minimises voltage drop and power loss, while high insulation resistance prevents leakage currents.
• Compact Design: Its miniature footprint (15mm x 33mm x 43mm) allows for installation in space-constrained environments.
• PCB Mountable: PC pin terminals are designed for secure and reliable soldering directly onto printed circuit boards.

This micro switch is a versatile component perfect for integrating into control panels, safety interlocks, position sensing, and a wide array of automation equipment where a dependable, low-current switch is required.
