KSJ0V41180SHLFTR is a spherical actuator tactile switch from the C&K KSJ Series, designed for momentary action with SPST normally open contact arrangement. This vertical insertion switch features a 3N (300 grams) actuation force with 100,000 operations life, an 80 Shore hardness actuator, and IP60 sealing for dust protection. The switch operates within a temperature range of -40°C to 85°C (silver contacts) or -40°C to 125°C (gold contacts), with electrical ratings including 32 VDC maximum voltage, 50 mA maximum current, and 1 VA maximum power. The spherical actuator design allows actuation force off center ±30° with regard to vertical, enabling compliant side actuation. Common applications include automotive systems, factory automation, security systems, and industrial equipment such as cranes, off-road vehicles, and railway systems.
