The KSL1M211 is a sealed tactile switch from the KSA & KSL Series designed for applications requiring reliable manual actuation in harsh environments. It features a long hard plastic actuator (KSL type) with manual bulk packaging insertion, silver contacts, and an operating force of 1.3 N (130 grams) rated for 100,000 operations. The switch provides IP60 sealing protection, SPST normally-open contact arrangement, and double overmolding on terminals with PC pins for robust mechanical retention. With a contact resistance below 100 mO, maximum voltage rating of 32 VDC, and operating temperature range of -40°C to +85°C, this switch is well-suited for automotive, industrial, and telecommunication network applications where sealed, durable switching is essential.
