The KSC441V2SPDLFS is a side-actuated sealed tactile switch from the KSC V2 series designed for SMD assembly with a 6.2 x 6.5 mm footprint and 3.9 mm soft actuator height. It features momentary action with SPST normally-open contact arrangement, silver-plated pin-in-paste terminals, and 3 SMD ground terminals, delivering an operating force of 3.5±1.0 N with 0.7±0.2 mm travel distance and 300,000 operations lifespan. Electrically, the switch supports 20 mV to 32 VDC with maximum power of 1 VA (silver contact), contact resistance =100 mO, and dielectric strength =250 Vrms, while operating reliably across -40°C to 85°C. The IP67-rated design with haptic adaptability, lead-free reflow compatibility, and RoHS/REACH compliance makes it ideal for industrial electronics, network equipment, and automotive applications requiring robust tactile feedback.
