C&K Components Inc. has rolled out its K12S series, a family of robust IP67-sealed SMT key switches. Some versions of the device can achieve one million life cycles, making them suitable for harsh environmental conditions commonly found in automotive, off-road transportation, industrial and medical applications. The key switches feature tactile feedback, and are available with LED illumination or double action and detect versions.

"The K12S Series rugged SMT key switches are available with a wide range of customization options to meet virtually any application requirement," said Gustavo Jimenez, product manager at C&K Components. "The IP67 sealing and extended life cycles make the K12S Series ideal for applications where in-field failure is unacceptable."

According to the company, the RoHS-compliant and halogen-free K12S Series' advanced design offers customers the flexibility to tailor force values, actuation travel options and provide single pole double throw custom solutions that meet application requirements. The series features an actuation force range of 1.5N to 9N with an overload of 100N and a total travel of 1.5mm.

The double-action design provides extremely good and sharp tactile feedback on both actions, the company said. The K12S Series features a maximum power rating of 3WDC and a min/max voltage of 2VDC to 30VDC with a min/max current rating of 10uA to100mA. The operating temperature ranges from -40C to 85C. The K12S Series is also available in an IP40-rated package for less demanding applications.
