C & K Silver Tactile Switch Button 0.75 mm, SPST 50mA 32 V dc Surface Mount IP50 IP Rating

The C & K KSR221G LFS tactile switch button is a high-quality surface mount switch featuring a silver actuator with a precise 0.75 mm length. This sub-miniature tactile switch offers a single pole single throw (SPST) contact configuration, rated for 50 mA current at 32 V dc, suitable for low-power electronic circuits.

Its compact dimensions (3.8 mm length, 7.3 mm width, 2.5 mm height) and IP50 ingress protection rating make it suitable for applications requiring basic dust resistance. The switch operates reliably across a wide temperature range from -40°C to 85°C, and offers a robust mechanical life of 200,000 operations, ensuring dependable performance in industrial, laboratory, and automation environments.

The actuator style is a silver-colored button requiring an operating force of 2 Newtons, providing tactile feedback for user interfaces such as keyboards, control panels, and electronic devices. The surface mount terminal type facilitates easy PCB assembly and soldering, with infrared reflow temperatures between 200 to 230°C for 10 to 15 seconds.

The switch is RoHS compliant, supporting environmentally responsible manufacturing practices. Manufactured in France, it leverages quality European engineering standards.
