ALPS Develops Multi Control Device, Slide Operation Type Stick Switch with 8-Contacts and Center Push Function



SSAF Series Contributes to Simpler Set Product Design

Duesseldorf, Germany, December 04, 2007 - ALPS ELECTRIC EUROPA GmbH has developed the SSAF series of multi control devices, with slide operation type stick switches (with 8-contacts and a center push function) for small portable devices such as mobile phones and handheld terminals.

In recent years, advances have been made in installing large-format displays in mobile phones, with an increasing number of handsets enabling users to browse Internet sites designed for access from computers. Unlike those for mobile phones, Web sites designed for browsing from computers contain information with numerous links that are hidden off the displayed screen. To view the whole page users need to press a button several times to move the screen or to select the linked URL. Thus, there have been demands for the introduction of a device that will enable mobile phone users to freely operate a cursor in the same way as a computer mouse, thereby making Internet browsing easier.

The SSAF series are multi control devices that combine an eight contact slide operation type switch with a centrally located push-switch function. With Alps Electric's proprietary sliding contact construction, which moves the operating part in various directions, the moving contacts will either make or break a circuit with any of the eight contacts, thus determining the direction of movement of the operating part. This enables free movement of the cursor on a mobile phone display.

In addition, input instructions are read as the contacts are switched on and off, so no special integrated circuit (IC) or software is required. With these features, the SSAF series will not only contribute to simplifying the design of set products input structures, but also reduce component design work and costs.

Using existing multi-directional input devices mainly involves tilting the operating part. For the SSAF series, however, Alps Electric has adopted an operating part with a sliding structure and realized the industry's thinnest body for a multi control device with multi-directional detection (height without operating part: 1.4mm; height including operating part: 3.0mm). Accordingly, the SSAF Series is compatible with small portable devices such as mobile phones and handheld terminals.

Furthermore, covering the operating part with rubber has realized smooth handling, providing users with a comfortable operating feel.
