C&K Components (Newton, MA) has designed the K12S series of robust, IP67-sealed SMT key switches for harsh environment applications. The switches are available with LED illumination or double action and detect versions. The series is RoHS-compliant and halogen- free. Users have the flexibility to tailor force values, actuation travel options, and provide single pole double throw (SPDT) custom solutions to meet application requirements. The series features an actuation force range of 1.5 N to 9N with an overload of 100N and a total travel time of 1.5 mm. The K12S Series device features a maximum power rating of 3 WDC and a minimum/maximum voltage of 2V – 30VDC with a minimum/maximum current rating of 10 μA to 100 mA. Operating temperature ranges from –40 °C to 85 °C. The series is also available in an IP40-rated package for less demanding applications.
