Multicomp Pro Snap Action Micro Switch, Pin Plunger, SPST-NO, 3A 125V AC

The Multicomp Pro Snap Action Micro Switch (MP005569) is a reliable and compact SPST-NO (Single Pole, Single Throw, Normally Open) switch designed for precise control in electronic circuits. Featuring a pin plunger actuator, it offers a crisp, definitive snap action for accurate and repeatable switching, making it ideal for applications requiring a distinct tactile feedback and dependable circuit interruption.

Constructed with high-quality materials, this miniature microswitch boasts excellent electrical characteristics, including a low contact resistance of 100mΩ for efficient current flow and a high insulation resistance of 100MΩ to ensure safety and prevent leakage. Its PC pin terminals facilitate easy and secure soldering onto printed circuit boards (PCBs), providing a stable and durable connection for long-term use.

With a maximum contact rating of 3A at 125V AC, this switch is suitable for controlling a variety of low-power AC loads. It requires a relatively light operating force, with a maximum of 90 grams-force (gf), allowing for sensitive activation. Its small form factor and robust snap-action mechanism make it a versatile component for designers and engineers.
