KSF0M411LFT is a soft actuated tactile switch from the KSF series designed for momentary action applications requiring sealed, low-profile switching. It features a 3.0 ± 0.75 N operating force with a 0.25 ± 0.1 mm travel distance and is rated for 100,000 operating cycles with an overload resistance of 40 N. The switch employs a single-pole, normally-open (SPST, N.O.) contact arrangement with through-hole terminals and offers IP60 or IP67 sealing for environmental protection. Electrical specifications include a maximum voltage of 32 VDC, maximum current of 50 mA (silver contact), contact resistance below 100 mO, and bounce time less than 1 ms. The device operates reliably across -40°C to 85°C (silver contact) or -40°C to 125°C (gold contact), making it suitable for low-profile keyboards, automotive interfaces, and industrial control systems.
