ALPS ELECTRIC EUROPE GmbH offers with its SKSK a double-action TACT Switch suitable for portable consumer devices such as digital cameras, mobile phones, and peripherals. The vertically operated SMD switch is remarkable for its low-profile design with dimensions of 3.5mm x 3.2mm x 0.6 mm (L x W x H) and a long operating life of up to 100,000 cycles.

It is rated for switching currents of 10μmA at 1VDC to a maximum of 50mA at 12VDC. It features operating forces of 0.6N (first position) and 1.6N (second position). The recommended operating area is specified with 0.7 mm in diameter. The operating temperature ranges from –40°C to +85°C.

Other technical specifications include travel length of 0.10mm or rather 0.25mm respectively, a maximum initial contact resistance of 100mΩ, an insulation resistance of 100MΩ at 100VDC, and a voltage proof of 100VAC per minute. The switch is suitable for reflow soldering and is available in minimum packing units of 10,000 pieces. For automatic mounting, it is packaged on embossed tape with a width of 12mm.

The miniaturization of mobile devices continues to advance. In line with this trend, demand is increasing for surface-mounted components and switches that do not sacrifice usability to compactness. With the SKSK ALPS has developed a low-profile tactile switch in response to this market need. The surface mount switch offers a clear tactile feedback when pressed.
