KSL1M411 is a sealed tactile switch from the KSL series designed for manual insertion applications requiring robust switching performance. The switch features a long hard plastic actuator (KSL type) with double overmolding on terminals, silver contacts, and an operating force of 3.0 N (300 grams) rated for 100,000 operations. It provides a travel-to-make distance of 0.6 ± 0.2 mm and maintains IP60 sealing protection with SPST normally-open contact arrangement. The device operates reliably across a temperature range of -40°C to +85°C and supports a maximum voltage of 32 VDC with a maximum current of 50 mA, making it suitable for automotive, industrial, and telecommunication applications where sealed, durable switching is essential.
