Product Description

The C & K KMR441G LFS tactile switch is a microminiature surface mount top actuated switch featuring an IP40 rating and a 2.5 mm actuator length. This SPST switch operates at 10mA and 32 V dc, making it suitable for a variety of precise electronic switching applications.

Its ultra-low current capabilities and excellent tactile feel provide reliable performance in harsh industrial, medical, and automotive environments. The tactile switch is engineered for a compact footprint of 4.2 mm length and 2.2 mm width, with a height of 2.5 mm, enabling easy integration on miniaturized circuit boards.

Designed for robust usage, it possesses a mechanical life expectancy of 100,000 operations and operates efficiently with a low actuation force of 4 Newtons. The switch is RoHS compliant, reflecting its environmentally safe construction.

It performs reliably within a temperature operating range from -40°C to 85°C and is suitable for surface mount technology (SMT) applications thanks to its surface terminal type. This momentary switch configuration allows temporary electrical contact when pressed, returning to its normal state upon release.

Typical use cases for this tactile switch include automotive electronics, medical devices, industrial equipment, and other electronic control systems requiring precise and durable actuation.

The switch offers a small footprint and ultra-low current switching capabilities. It provides excellent tactile response with minimal actuation force. IP40 rating ensures protection against solid particles. Manufactured under strict quality standards in France.
