Alps Electric has released the industry's thinnest double-action TACT switches for applications such as shutter buttons for digital still and video cameras, and in screen scroll buttons used in mobile phones and other mobile information terminals By making alterations to the company's proprietary moulding process and using new insulation sheet materials, the SKRN Series of TACT switches are a mere 0.9mm thick, some 55% thinner than the company's SKQA Series of TACT switches

Detector switches seek automotive applications
The SPVQ4 Series comprises waterproof, high-contact-reliability detector switches that have a long stroke and can withstand severe conditions.
Automotive AM/FM tuners boast high sensitivity
With the TFTC7 series Alps Electric Europa now offers a family of compact, low-profile automotive AM/FM tuners, boasting high sensitivity of -1dBu and high S/N ratio of 66dB.
The switches have a double-action feature, with two contact points in one circuit that contains upper and lower blade spring contact points, allowing digital cameras to automatically focus and survey a shot with a light press of the shutter button, and then record the image when the shutter is fully depressed.
The new shape employed for the upper blade spring contact point enables the SKRN Series to have a life cycle of 30,000 cycles, 1.5 times more than previous products.
Thanks to this double-action feature and dimensions of 6.0 x 6.0 x 0.9mm, the SKRN series has applications in two-speed screen scroll buttons for cell phones and mobile information terminals, as well as digital cameras.
The thin profile of the switches will allow set manufacturers to reduce the size of devices, helping them to meet demand for portable devices with higher resolution, smaller and thinner body sizes and a wider variety of models.
Shipments of digital cameras in Japan from January to June 2001 exceeded those of conventional cameras, and are expected to maintain this growth rate.
Alps Electric will start shipping samples costing 70 Yen each towards the end of December 2001.
